What Is a JavaScript Accordion?

A JavaScript accordion is an interactive content component where users click a header, question, label, or button to reveal hidden content below it. When the same header is clicked again, the content can close. Accordions are commonly used for FAQ sections, product information, support answers, mobile filters, pricing questions, documentation topics, settings panels, and compact landing page sections.

The main purpose of an accordion is to organize information without making the page feel too long. Instead of showing every answer, paragraph, specification, or setting at once, an accordion keeps the layout clean and lets visitors expand only the content they want to read.

A JavaScript accordion can be very simple or highly advanced. A basic version may toggle one answer open and closed. A more advanced version may include smooth height animation, one-open-at-a-time behavior, nested panels, icons that rotate, keyboard support, dynamic content, search filtering, active states, URL hash support, or accessible ARIA attributes.

Why JavaScript Accordions Matter

JavaScript accordions matter because many modern pages need to show a lot of information without overwhelming the visitor. A long FAQ section, product specification table, pricing explanation, help center, mobile filter panel, or onboarding checklist can quickly become hard to scan if everything is open at once.

They reduce visual clutter by hiding secondary content until the user needs it.
They improve FAQ sections by making questions easier to scan and answers easier to open.
They help ecommerce pages by organizing product details, shipping info, sizing, materials, warranty text, and reviews.
They support mobile layouts by turning long sections, filters, menus, and settings into compact expandable panels.
They improve documentation UX by grouping related topics, steps, examples, and explanations into readable blocks.

Accordions are especially useful when users do not need every piece of content at the same time. Someone reading a pricing page may only care about billing questions. Someone viewing a product page may only want size details. Someone using a dashboard may only need one settings group. A well-built JavaScript accordion makes that interaction faster and cleaner.

JavaScript Accordion vs CSS Accordion

A CSS accordion can work well for simple show-and-hide content, especially when using checkbox, radio, details, summary, or hover-based patterns. However, JavaScript gives you more control over behavior, state, animation, accessibility, and logic.

With JavaScript, you can decide whether multiple panels can stay open, whether opening one panel should close the others, whether the first item should be open by default, how icons should animate, how keyboard interaction should work, and how the accordion should respond to dynamic content changes.

Use a CSS accordion when the component is very simple and does not need advanced logic.
Use a JavaScript accordion when you need custom open and close behavior, animation control, ARIA updates, or dynamic state.
Use one-open-at-a-time logic for FAQ sections, pricing questions, and compact information groups.
Use multi-open logic when users may need to compare several answers, settings, or product details.
Use nested accordions carefully when documentation, menus, filters, or help centers need multiple content levels.

This guide focuses on JavaScript accordion examples, so every demo will include visible JavaScript, HTML, and CSS code. The examples are designed to be copy-paste friendly, easy to customize, and different in layout, style, structure, and interaction pattern.

What Should a Good JavaScript Accordion Include?

A good JavaScript accordion should feel obvious, fast, and stable. Users should understand which parts are clickable, which panel is open, and what happened after they clicked. The content should open smoothly, the active state should be visible, and the layout should remain usable on desktop, tablet, and mobile.

Clear clickable headers

Accordion buttons should look interactive, with strong labels, icons, arrows, or plus signs that show users they can expand the content.

Visible active state

The open accordion item should look different from closed items, so users know which section they are currently reading.

Smooth open and close behavior

JavaScript can control height, classes, icons, and state so the accordion feels polished instead of abrupt or broken.

Responsive mobile layout

Accordions should be easy to tap on small screens, with readable text, enough spacing, and no cramped controls.

Before building an accordion, decide how the component should behave. Should one item open at a time, or should users be able to open multiple items? Should the first panel be open by default? Should the accordion use a plus icon, chevron, number, badge, or progress indicator? Should it work as a FAQ block, product information section, mobile menu, dashboard panel, or documentation layout?

Use button elements for accordion triggers so the clickable areas are more accessible and predictable.
Add active classes to open items so CSS can style the selected state clearly.
Update icons when panels open and close, such as plus to minus or chevron rotation.
Use smooth animation carefully so content expands nicely without layout jumps.
Keep panel content readable with enough spacing, line height, and contrast.
Support keyboard users with real buttons, focus states, and logical tab order.
Avoid hiding important content if users must see it immediately to complete a task.
Test long answers because real FAQ, product, and documentation content is often longer than demo text.
Make touch targets large enough for mobile users who tap accordion headers with a thumb.
Keep JavaScript scoped so multiple accordions can work on the same page without conflicts.

You can combine JavaScript accordions with many other interface patterns. FAQ accordions work well with modern CSS forms on support pages, product accordions can be placed inside modern CSS cards, mobile filter accordions can pair with JavaScript search filters, and documentation accordions can be combined with layouts from our modern CSS layouts guide.

30 JavaScript Accordion Examples

Now let’s look at 30 JavaScript accordion examples for real website projects. Each example uses a different layout, visual style, open and close behavior, content structure, animation style, icon pattern, FAQ format, product details section, dashboard panel, mobile filter layout, nested structure, or responsive accordion approach, so you can build professional expandable UI components with visible JavaScript, HTML, and CSS code.

1. Modern FAQ Accordion

A modern FAQ accordion is one of the most common JavaScript accordion patterns for websites, SaaS pages, service pages, ecommerce stores, and landing pages. It keeps questions visible while hiding longer answers until the user clicks.

This example uses a clean FAQ card layout with smooth open and close behavior, plus and minus icons, active item styling, and one-open-at-a-time JavaScript logic.

One-open-at-a-time accordion behavior
Smooth FAQ answer expansion
Plus and minus icon update
Active state styling
Responsive FAQ layout

Example 01

Where should I use accordions? +

Accordions work well for FAQ sections, product details, pricing questions, documentation pages, mobile filters, and dashboard settings panels.

Can multiple accordion items stay open? +

Yes. JavaScript can be written for one-open-at-a-time accordions or multi-open accordions depending on the user experience you want.

Yes. The layout, spacing, font sizes, and clickable buttons are designed to stay readable and easy to tap on smaller screens.

JavaScript

(function () {
  const accordion = document.querySelector("[data-vb-accordion-one]");
  if (!accordion) return;

  const items = Array.from(accordion.querySelectorAll(".vb-accordion-one-item"));

  function closeItem(item) {
    const trigger = item.querySelector(".vb-accordion-one-trigger");
    const panel = item.querySelector(".vb-accordion-one-panel");
    const icon = trigger.querySelector("strong");

    item.classList.remove("is-open");
    trigger.setAttribute("aria-expanded", "false");
    icon.textContent = "+";
    panel.style.maxHeight = "0px";
  }

  function openItem(item) {
    const trigger = item.querySelector(".vb-accordion-one-trigger");
    const panel = item.querySelector(".vb-accordion-one-panel");
    const icon = trigger.querySelector("strong");

    item.classList.add("is-open");
    trigger.setAttribute("aria-expanded", "true");
    icon.textContent = "−";
    panel.style.maxHeight = panel.scrollHeight + "px";

    const trigger = item.querySelector(".vb-accordion-one-trigger");

    trigger.addEventListener("click", function () {
      const isOpen = item.classList.contains("is-open");

      items.forEach(closeItem);

      if (!isOpen) {
        openItem(item);
      }
    });

This modern FAQ accordion is a strong base pattern for support sections, pricing pages, homepage FAQ blocks, service pages, and landing pages where visitors need quick answers without scrolling through long visible text.

2. Product Details Accordion

A product details accordion helps ecommerce pages organize important information such as specifications, shipping, materials, care instructions, warranty details, and return policy content. It keeps product pages cleaner while still making detailed information available.

This example uses a split ecommerce layout with a product preview card on the left and a vertical accordion on the right. The JavaScript allows multiple sections to stay open, which is useful when shoppers want to compare details before buying.

Multi-open accordion behavior
Product page information layout
Animated chevron rotation
Specification and shipping panels
Professional ecommerce-style design

This product details accordion is useful for ecommerce product pages, catalog landing pages, service packages, digital products, course pages, and any page where users need structured details without a long block of visible text.

3. Dark Glassmorphism Accordion

A dark glassmorphism accordion is a strong choice for SaaS landing pages, AI tools, crypto dashboards, premium product pages, and futuristic website sections. It uses translucent panels, blurred backgrounds, glowing borders, and smooth JavaScript toggle behavior.

This example uses a dark gradient background, glass-style accordion rows, numbered labels, glowing active states, and one-open-at-a-time behavior. The design is intentionally different from the previous examples, with softer pill-shaped panels and neon visual details.

One-open-at-a-time JavaScript behavior
Numbered accordion rows
Glowing active border effect
Responsive premium-style layout

Example 03

Dark Glassmorphism Accordion

Use a glowing glass accordion layout for futuristic FAQ, SaaS, AI tool, or dashboard sections.

01 Can I use this accordion on a SaaS landing page?

Yes. This layout works well for product FAQs, feature explanations, onboarding questions, pricing details, and premium landing page sections.

02 What makes glassmorphism different?

Glassmorphism uses translucent backgrounds, subtle borders, blurred layers, and soft glowing effects to create depth without heavy visual blocks.

03 Does this design support long content?

The JavaScript calculates the panel height dynamically, so longer answers, feature lists, short paragraphs, or documentation notes can open smoothly.

04 Can I change the colors?

Yes. You can adjust the background gradients, glowing borders, text colors, and orb effects to match your brand or website theme.

JavaScript

(function () {
  const accordion = document.querySelector("[data-vb-accordion-three]");
  if (!accordion) return;

  const items = Array.from(accordion.querySelectorAll(".vb-accordion-three-item"));

  function closeItem(item) {
    const trigger = item.querySelector(".vb-accordion-three-trigger");
    const panel = item.querySelector(".vb-accordion-three-panel");

    item.classList.remove("is-open");
    trigger.setAttribute("aria-expanded", "false");
    panel.style.maxHeight = "0px";
  }

  function openItem(item) {
    const trigger = item.querySelector(".vb-accordion-three-trigger");
    const panel = item.querySelector(".vb-accordion-three-panel");

    item.classList.add("is-open");
    trigger.setAttribute("aria-expanded", "true");
    panel.style.maxHeight = panel.scrollHeight + "px";
  }

  items.forEach(function (item) {
    const trigger = item.querySelector(".vb-accordion-three-trigger");

    trigger.addEventListener("click", function () {
      const isOpen = item.classList.contains("is-open");

      items.forEach(closeItem);

      if (!isOpen) {
        openItem(item);
      }
    });
  });

  const openDefault = accordion.querySelector(".vb-accordion-three-item.is-open");
  if (openDefault) {
    openItem(openDefault);
  }

  window.addEventListener("resize", function () {
    const openItemElement = accordion.querySelector(".vb-accordion-three-item.is-open");
    if (openItemElement) {
      openItem(openItemElement);
    }
  });
})();

This dark glassmorphism accordion is useful for modern SaaS websites, AI product pages, crypto dashboards, premium service sections, and landing pages that need a more futuristic expandable content style.

4. Timeline Step Accordion

A timeline step accordion is useful when content needs to follow a process, roadmap, onboarding flow, project sequence, or service timeline. Each accordion item represents one stage, and users can open the step they want to read.

This example uses a vertical timeline layout with connected dots, offset cards, sharp diagonal labels, and multi-open JavaScript behavior. It looks different from a standard FAQ because the accordion items behave like expandable process steps.

Timeline-style accordion structure
Multi-open expandable steps
Connected vertical progress line
Diagonal step labels
Useful for processes, onboarding, and roadmaps

Example 04

Timeline Step Accordion

Expand each process step to reveal details, deliverables, and useful context inside a vertical timeline layout.

5. Minimal Border Accordion

A minimal border accordion works well for clean editorial websites, documentation pages, product FAQs, portfolio pages, and modern service pages where the design should feel lightweight instead of visually heavy.

This example uses thin borders, small uppercase labels, spacious typography, line-based dividers, and a simple arrow button. The JavaScript uses one-open-at-a-time behavior and keeps the visual style calm and professional.

Minimal line-based accordion design
One-open-at-a-time behavior

Example 05

Minimal Border Accordion

A quiet accordion layout with thin lines, simple spacing, and clear expandable content.

Guide How does the accordion open? →

The JavaScript listens for a click on each accordion button, closes the other items, opens the selected item, and updates the content height smoothly.

Layout Why use a minimal accordion? →

A minimal accordion keeps the page light and readable. It is a good fit when content clarity is more important than decorative effects.

Content What type of content fits here? →

This style works for documentation notes, support questions, course lessons, service explanations, legal text summaries, and clean FAQ pages.

Mobile Does the layout work on phones? →

Yes. The desktop grid becomes a single-column button layout on smaller screens, keeping the labels and titles readable.

This minimal border accordion is useful for documentation pages, editorial websites, knowledge bases, product information sections, and service pages where the interface should stay clean and content-focused.

6. Color Block Category Accordion

A color block category accordion uses strong visual blocks to separate different content categories. This is useful for dashboards, learning platforms, feature sections, product guides, service pages, and support centers where each accordion item belongs to a clear topic.

This example looks different from a normal FAQ accordion because each item has its own color stripe, icon badge, clipped corner, and card-style content area. The JavaScript allows multiple category blocks to stay open at the same time.

Color-coded accordion categories
Multi-open JavaScript behavior
Icon badge and clipped corner design
Strong visual separation between items
Useful for dashboards, guides, and feature sections

Example 06

Color Block Category Accordion

Open several colorful content categories at once and keep each topic visually separated.

⚙ Setup options Installation, configuration, and first steps +

Use this section to explain setup requirements, recommended defaults, onboarding steps, and the first actions a user should take.

✓ Best practices Recommended usage and cleaner workflows +

Use best-practice blocks to guide users toward better decisions, cleaner layouts, faster workflows, and more reliable interaction patterns.

! Common issues Problems, mistakes, and troubleshooting +

This block can explain layout bugs, missing content, animation issues, JavaScript conflicts, or mobile problems users may run into.

★ Advanced tips Extra ideas for polished UI components +

Advanced accordion sections can include nested panels, search support, keyboard controls, default open states, and custom animation timing.

This color block category accordion is useful for feature explainers, learning modules, product guides, dashboard help panels, service categories, and support pages where each topic should feel visually distinct.

7. Mobile Filter Accordion

A mobile filter accordion is useful for ecommerce stores, directories, listing pages, travel websites, real estate pages, and product catalogs where filter controls take too much space on smaller screens.

This example uses a compact mobile-style filter drawer layout with expandable filter groups. The design uses a phone-like frame, rounded pill chips, a sticky action bar, and multi-open JavaScript behavior so users can open several filter groups at once.

Mobile-friendly filter accordion
Multi-open filter groups
Filter chips and checkbox-style options
Sticky apply/reset action bar
Useful for ecommerce and listing pages

8. Split Image Content Accordion

A split image content accordion combines expandable text with a strong visual area. It is useful for agency websites, service pages, product showcases, course landing pages, restaurant pages, travel sections, and feature explainers.

This example uses a split-screen layout with an abstract image card on the left and stacked accordion panels on the right. The visual card updates through active styling, while the accordion uses one-open-at-a-time JavaScript behavior.

Split image and accordion layout
One-open-at-a-time behavior
Large visual illustration card
Angled content panels
Useful for services, products, and feature sections

Example 08

Split Image Content Accordion

Use a visual feature area beside expandable content panels for product or service explanations.

01 Feature overview View

Explain the main value of a product, service, or interface section in a compact panel without making the page too long.

02 Design details View

Use this panel to describe colors, layout choices, animations, responsive behavior, and important visual details.

03 Technical setup View

The JavaScript controls active classes, ARIA values, max-height animation, and closing other panels when one opens.

04 Best use cases View

This split accordion works well for service highlights, product features, course modules, agency processes, and startup landing pages.

JavaScript

(function () {
  const accordion = document.querySelector("[data-vb-accordion-eight]");
  if (!accordion) return;

  const items = Array.from(accordion.querySelectorAll(".vb-accordion-eight-item"));

  function closeItem(item) {
    const button = item.querySelector(".vb-accordion-eight-trigger");
    const panel = item.querySelector(".vb-accordion-eight-panel");

    item.classList.remove("is-open");
    button.setAttribute("aria-expanded", "false");
    panel.style.maxHeight = "0px";
  }

  function openItem(item) {
    const button = item.querySelector(".vb-accordion-eight-trigger");
    const panel = item.querySelector(".vb-accordion-eight-panel");

    item.classList.add("is-open");
    button.setAttribute("aria-expanded", "true");
    panel.style.maxHeight = panel.scrollHeight + "px";
  }

  items.forEach(function (item) {
    const button = item.querySelector(".vb-accordion-eight-trigger");

    button.addEventListener("click", function () {
      const isOpen = item.classList.contains("is-open");

      items.forEach(closeItem);

      if (!isOpen) {
        openItem(item);
      }
    });
  });

  const defaultItem = accordion.querySelector(".vb-accordion-eight-item.is-open");
  if (defaultItem) {
    openItem(defaultItem);
  }

  window.addEventListener("resize", function () {
    const open = accordion.querySelector(".vb-accordion-eight-item.is-open");
    if (open) {
      openItem(open);
    }
  });
})();

This split image content accordion is useful for landing pages, product features, agency service sections, startup pages, course previews, portfolio case studies, and any layout where expandable text should be supported by a strong visual block.

9. Dashboard Settings Accordion

A dashboard settings accordion is useful for admin panels, SaaS products, account pages, user dashboards, plugin settings screens, and app configuration pages. It keeps settings grouped into clear sections instead of showing every option at once.

This example uses a professional dashboard-style layout with a left settings summary, status badges, toggle switches, and expandable settings panels. The design is different from the previous examples because it looks like a real app settings screen rather than a marketing or FAQ section.

Dashboard-style accordion layout
Multi-open settings panels
Toggle switch UI elements
Status badges and app-style cards
Useful for admin panels and SaaS dashboards

JavaScript

(function () {
  const accordion = document.querySelector("[data-vb-accordion-nine]");

  function updateItem(item) {
    const button = item.querySelector(".vb-accordion-nine-trigger");
    const panel = item.querySelector(".vb-accordion-nine-panel");
    const badge = button.querySelector("em");
    const isOpen = item.classList.contains("is-open");

    button.setAttribute("aria-expanded", isOpen ? "true" : "false");
    badge.textContent = isOpen ? "Active" : "Open";
    panel.style.maxHeight = isOpen ? panel.scrollHeight + "px" : "0px";
  }

  items.forEach(function (item) {
    const button = item.querySelector(".vb-accordion-nine-trigger");

    button.addEventListener("click", function () {
      item.classList.toggle("is-open");
      updateItem(item);

10. Pricing FAQ Accordion

A pricing FAQ accordion helps answer common buying questions near a pricing section. It is useful for SaaS pricing pages, agency service packages, subscription products, memberships, hosting plans, and digital product sales pages.

This example uses a premium pricing layout with a price card, highlighted plan badge, angled FAQ rows, and one-open-at-a-time JavaScript behavior. The visual structure is different from standard FAQ accordions because it connects the expandable questions directly with a conversion-focused pricing card.

Pricing-focused FAQ accordion
One-open-at-a-time behavior
Plan card and CTA section
Angled question rows
Useful for SaaS, subscriptions, and service packages

Pricing FAQ Accordion

Answer purchase questions beside a pricing card and keep the conversion section compact.

Can I cancel anytime? +

Yes. Users can cancel the subscription whenever they want. The plan remains active until the end of the current billing period.

Do I get future updates? +

Yes. Active users receive product updates, new examples, improvements, bug fixes, and upgraded UI components as they are released.

Can I use this for client projects? +

Yes. You can adapt the layouts and JavaScript patterns for client websites, landing pages, dashboards, and custom interface projects.

Is the code beginner friendly? +

The code uses vanilla JavaScript, structured HTML, and plain CSS, so it is easier to understand, edit, and reuse without extra frameworks.

This pricing FAQ accordion is useful for SaaS pricing pages, service packages, membership plans, hosting offers, digital product pages, course pricing sections, and conversion-focused landing pages.

11. Documentation Sidebar Accordion

A documentation sidebar accordion is useful for help centers, developer docs, knowledge bases, plugin documentation, API guides, and tutorial libraries. It keeps many navigation topics compact while still letting users expand the section they need.

This example uses a documentation-style layout with a sticky-looking left sidebar, active navigation groups, small status labels, and one-open-at-a-time JavaScript behavior. The design is intentionally more structured and technical than a standard FAQ accordion.

12. Neon Card Stack Accordion

A neon card stack accordion creates a bold visual style for modern landing pages, creative portfolios, AI tools, gaming websites, tech products, and promotional sections. It uses overlapping cards, neon borders, and animated active states.

This example uses a stacked card layout with offset panels, glowing category badges, and multi-open JavaScript behavior. Each accordion row feels like a separate interactive card instead of a standard list item.

    button.setAttribute("aria-expanded", isOpen ? "true" : "false");
    panel.style.maxHeight = isOpen ? panel.scrollHeight + "px" : "0px";
  }

  items.forEach(function (item) {
    const button = item.querySelector(".vb-accordion-twelve-trigger");

    button.addEventListener("click", function () {
      item.classList.toggle("is-open");

13. Support Center Accordion

A support center accordion is useful for customer help pages, SaaS support sections, ecommerce help centers, plugin support pages, and service websites where users need quick answers grouped by topic.

This example uses a help-desk inspired layout with a support ticket card, category badges, soft rounded panels, and one-open-at-a-time JavaScript behavior. The design is calmer and more service-oriented than the previous neon and dashboard examples.

Support Center Accordion

Organize help questions into expandable support topics with clear category labels.

Account How do I reset my password?

Go to the login page, choose the password reset option, enter your account email, and follow the secure link sent to your inbox.

Billing Where can I download invoices?

Invoices are usually available inside the billing section of the account dashboard. You can download PDF invoices for each completed payment.

Technical Why is my component not opening?

Check that the JavaScript selector matches the HTML attribute, the script is loaded after the HTML, and no duplicate class names conflict with another accordion.

Updates How do I get product updates?

Active customers can receive updates through the account dashboard, download area, email notifications, or the product update page.

14. Horizontal Feature Accordion

A horizontal feature accordion is useful for landing pages, SaaS feature sections, app showcases, product explainers, and homepage sections where several feature cards need to share one visual row.

This example uses a horizontal card row on desktop and turns into stacked cards on mobile. The active card expands visually, while the JavaScript switches the selected feature and updates ARIA states without using external libraries.

Horizontal feature accordion layout
Active card expands on desktop
One-active-card behavior
Responsive stacked mobile layout
Useful for features, services, and product highlights

Example 14

Horizontal Feature Accordion

Click a feature card to expand it and highlight the selected value proposition.

01 Fast setup

Launch a clean accordion interface quickly with scoped JavaScript, simple HTML, and responsive CSS.

View example

02 Reusable code

Use unique class names and scoped selectors so multiple accordions can exist on the same page.

View example

03 Responsive UI

The horizontal desktop layout changes into a readable stacked layout on smaller screens.

View example

04 Clear states

Active styling, expanded content, and ARIA attributes help users understand which feature is selected.

View example

JavaScript

(function () {
  const accordion = document.querySelector("[data-vb-accordion-fourteen]");
  if (!accordion) return;

  const cards = Array.from(accordion.querySelectorAll(".vb-accordion-fourteen-card"));

  function activateCard(selectedCard) {
    cards.forEach(function (card) {
      const button = card.querySelector(".vb-accordion-fourteen-trigger");
      const isSelected = card === selectedCard;

      card.classList.toggle("is-open", isSelected);
      button.setAttribute("aria-expanded", isSelected ? "true" : "false");
    });
  }

  cards.forEach(function (card) {
    const button = card.querySelector(".vb-accordion-fourteen-trigger");

    button.addEventListener("click", function () {
      activateCard(card);
    });
  });

  const defaultCard = accordion.querySelector(".vb-accordion-fourteen-card.is-open") || cards[0];

15. Nested Accordion Menu

A nested accordion menu is useful when content has more than one level, such as documentation categories, dashboard navigation, mobile menus, product filters, learning modules, and help center topics.

This example uses a two-level accordion structure with parent sections and child panels. The design uses a compact navigation layout, nested indentation, soft shadows, and separate JavaScript logic for parent and child accordion items.

Two-level nested accordion structure
Parent and child toggle behavior
Compact navigation-style design
Indented child panels
Useful for docs, menus, filters, and learning platforms

Example 15

Nested Accordion Menu

Open parent categories and reveal nested child accordions inside each section.

16. Searchable FAQ Accordion

A searchable FAQ accordion combines live search filtering with expandable JavaScript FAQ panels. It is useful for support pages, help centers, product FAQs, documentation pages, and long FAQ sections where users need to find answers quickly.

This example uses a search input, result count, no-results message, and accordion behavior. The layout has a clean support-search design, and the JavaScript filters FAQ items while still allowing users to expand matching answers.

FAQ search input
Live filtering by question and answer text
Result count and empty state
One-open-at-a-time accordion behavior
Useful for large FAQ and help sections

This searchable FAQ accordion is ideal for large FAQ pages, support centers, documentation sections, product help pages, onboarding resources, and any long answer section where users need both search and expandable content.

17. Comparison Accordion

A comparison accordion is useful when visitors need to compare options, plans, services, product versions, features, or packages without reading a long comparison table on mobile.

This example uses a side-by-side comparison layout on desktop and a compact accordion structure on smaller screens. Each expandable row compares two options with clear labels, checkmarks, and a bold active state.

Comparison-focused accordion layout
One-open-at-a-time behavior
Two-column feature comparison
Checkmark and difference labels
Useful for plans, services, and products

Example 17

Compare two options inside expandable rows without showing a large table at once.

This comparison accordion is useful for pricing plans, service packages, product versions, feature comparisons, mobile comparison sections, and landing pages where users need structured differences without a large table.

18. Notification Accordion

A notification accordion is useful for dashboards, admin panels, account pages, app inboxes, update centers, CRM screens, and project management interfaces where messages need to expand into more detail.

This example uses an inbox-inspired accordion with unread indicators, message timestamps, priority badges, and multi-open behavior. It has a completely different visual feel from FAQ or content accordions because it is designed like a compact notification center.

Notification center accordion layout
Multi-open message behavior
Unread dots and timestamps
Priority and status badges
Useful for dashboards, inboxes, and admin screens

Example 18

Notification Accordion

Expand notification rows to read more details without leaving the dashboard.

19. Course Module Accordion

A course module accordion is useful for online course pages, learning platforms, coaching websites, workshop pages, lesson previews, and educational landing pages where lessons need to stay organized and easy to scan.

This example uses a learning-dashboard style with lesson progress, module numbers, duration labels, progress bars, and multi-open JavaScript behavior. It is visually different from standard FAQ accordions because it feels like a structured course curriculum preview.

Course curriculum accordion layout
Multi-open module behavior
Lesson duration and progress indicators
Learning platform visual style
Useful for courses, workshops, and tutorials

This course module accordion is useful for online courses, tutorial libraries, workshop landing pages, coaching programs, digital learning platforms, and educational websites that need structured lesson previews.

20. Restaurant Menu Accordion

A restaurant menu accordion is useful for restaurant websites, cafe pages, food delivery menus, catering services, recipe sections, and hospitality landing pages where food categories need to stay compact and easy to browse.

This example uses a warm restaurant-style layout with menu categories, price tags, decorative dividers, and one-open-at-a-time JavaScript behavior. The design is intentionally different from dashboard or SaaS accordions because it uses a hospitality-inspired visual style.

Restaurant menu accordion layout
One-open-at-a-time category behavior

21. Product Details Accordion

A product details accordion is useful for ecommerce product pages where technical information, shipping details, materials, sizing, warranty information, and care instructions should stay organized without making the product page too long.

This example uses a premium product page layout with a product card, stock badge, specification rows, and one-open-at-a-time JavaScript behavior. It is designed for ecommerce and product information sections rather than a normal FAQ block.

22. Event Schedule Accordion

An event schedule accordion is useful for conferences, webinars, workshops, festivals, online summits, meetups, and event landing pages where users need to browse sessions without seeing the full agenda at once.

This example uses an agenda-style layout with time blocks, speaker labels, session tracks, and multi-open JavaScript behavior. It has a clear event schedule structure instead of a generic question-and-answer layout.

This event schedule accordion is useful for conferences, webinars, workshops, online events, product launches, festivals, meetups, training days, and event landing pages that need a compact expandable agenda.

23. Timeline Accordion

A timeline accordion is useful for project roadmaps, company history sections, launch timelines, onboarding flows, process pages, and case studies where events should be shown in a chronological order.

This example uses a vertical timeline with connected markers, year labels, milestone cards, and one-open-at-a-time JavaScript behavior. The layout feels like a roadmap instead of a normal stacked FAQ accordion.

Timeline-style accordion layout
Connected vertical milestone line
One-open-at-a-time interaction
Year labels and milestone details
Useful for roadmaps, history, and process sections

24. Magazine Story Accordion

A magazine story accordion is useful for editorial websites, online magazines, storytelling landing pages, article collections, news features, portfolio case studies, and content-rich brand pages.

This example uses a large editorial cover panel, numbered story cards, image-like CSS blocks, pull-quote styling, and multi-open JavaScript behavior. It is visually built like a magazine feature instead of a support, dashboard, or product accordion.

Editorial magazine-style accordion
Multi-open JavaScript behavior
Large story cover and article cards
Pull-quote and feature labels

Feature 03 Visual direction +

Use this section for visual decisions, layout notes, typography choices, color direction, and interface details.

Feature 04 Final outcome +

25. Analytics Report Accordion

An analytics report accordion is useful for dashboards, SEO reports, marketing summaries, SaaS analytics screens, client reports, performance audits, and admin panels where data sections need to be opened one by one.

This example uses a data-report layout with metric cards, chart-like CSS bars, percentage badges, and one-open-at-a-time JavaScript behavior. The visual style is built around analytics and reporting, not standard FAQ rows.

Analytics dashboard accordion design
One-open-at-a-time report sections

Useful for reports, dashboards, and audits

26. Mobile App Settings Accordion

A mobile app settings accordion is useful for mobile app landing pages, profile screens, account settings pages, app dashboards, onboarding previews, and product UI sections that need compact expandable settings.

This example looks like a phone screen with segmented settings cards, toggle rows, app-style icons, and multi-open JavaScript behavior. It is intentionally designed as a mobile interface preview instead of a wide website accordion.

Phone-style app settings accordion
Multi-open settings behavior
Toggle controls and icon rows
Mobile-first visual structure
Useful for app UI and profile settings sections

This mobile app settings accordion is useful for mobile app landing pages, user account screens, app dashboards, profile settings, privacy settings, notification controls, and mobile-first UI examples.

27. File Upload Accordion

A file upload accordion is useful for dashboards, document portals, onboarding forms, client areas, support ticket pages, job application forms, and admin panels where users need to upload different types of files in a structured way.

This example uses a document-upload layout with dashed drop zones, upload status chips, file type labels, and one-open-at-a-time JavaScript behavior. The design is intentionally different from normal FAQ accordions because it feels like a practical file management interface.

28. Real Estate Listing Accordion

A real estate listing accordion is useful for property pages, apartment listings, booking websites, rental platforms, real estate landing pages, and neighborhood guides where property details should be compact but easy to explore.

This example uses a property-listing style with a visual property card, room statistics, price badge, amenity rows, and multi-open JavaScript behavior. It looks like a real estate interface rather than a generic web accordion.

29. Pricing Add-On Accordion

A pricing add-on accordion is useful for SaaS pricing pages, checkout pages, subscription plans, hosting packages, plugin pricing, service bundles, and product upsell sections where optional extras need to be explained clearly.

This example uses a checkout-inspired layout with add-on cards, price pills, selected states, a total summary, and one-open-at-a-time JavaScript behavior. It is designed like a pricing configurator instead of a standard FAQ accordion.

30. Complete Responsive Accordion Section

A complete responsive accordion section is useful when a page needs a polished final accordion block with intro text, category tabs, expandable answers, visual cards, call-to-action buttons, and a layout that works across desktop, tablet, and mobile screens.

This final example combines a full landing-page section layout with category buttons, one-open-at-a-time accordion behavior, a side visual panel, and responsive styling. It is designed as a complete website section rather than a small standalone component.

Complete responsive accordion section
Category buttons and expandable answers
One-open-at-a-time JavaScript behavior
Side visual panel and CTA buttons
Useful for landing pages, FAQ sections, and service pages

Example 30

Complete Responsive Accordion Section

Build a polished accordion section with category navigation, expandable answers, supporting visuals, and responsive layout behavior.

How can I use this accordion section?

You can use this section for FAQ pages, service pages, SaaS landing pages, product pages, support sections, onboarding pages, or documentation introductions.

Does it work on mobile screens?

Yes. The layout changes from a two-column section to a single-column structure, while spacing, buttons, and panels stay readable on small screens.

Can I place multiple accordions on one page?

Yes, if each accordion uses scoped class names and a unique data attribute. This keeps JavaScript selectors from conflicting with other examples.

Why use JavaScript instead of only CSS?

JavaScript gives better control over ARIA states, one-open-at-a-time behavior, dynamic heights, resize updates, and more advanced UI logic.

JavaScript Accordion Best Practices

JavaScript accordions work best when they make a page easier to scan without hiding information users need immediately. A strong accordion component should have clear clickable headers, readable expanded content, visible active states, smooth open and close behavior, and responsive spacing that works on desktop, tablet, and mobile screens.

For business websites, FAQ pages, ecommerce product pages, service pages, SaaS landing pages, dashboards, documentation sections, and support pages, accordions are useful because they organize long content into smaller sections. The goal is not to add animation for decoration, but to help visitors find the right answer, feature, setting, product detail, or pricing information faster.

Use clear accordion labels

Each accordion header should describe exactly what users will find inside, such as shipping details, pricing questions, product specs, setup steps, or support answers.

Make the whole header clickable

Users should not need to click a tiny icon. Make the full question, title, or accordion row clickable for a better desktop and mobile experience.

Show a strong open state

The active accordion item should stand out with a different border, background, icon state, shadow, or label style.

Use real button elements

Accordion triggers should be buttons, not random divs, because buttons are easier to use with keyboards and assistive technologies.

Keep JavaScript scoped

Use a unique wrapper and class names so multiple accordions can work on the same page without CSS or JavaScript conflicts.

Test long real content

Real FAQ answers, product descriptions, documentation text, and pricing notes are often much longer than demo text, so test with realistic content.

For most FAQ sections and landing pages, one-open-at-a-time behavior is a good choice because it keeps the page compact. For dashboards, documentation, product details, course modules, and settings panels, multi-open behavior can be better because users may want to compare several open sections at once.

Use one-open-at-a-time accordions for FAQs, pricing questions, service pages, and short support sections.
Use multi-open accordions for documentation, dashboards, product details, settings, and comparison-style content.
Use clear icons such as plus/minus, chevrons, arrows, labels, badges, or active indicators.
Keep animations short so the accordion feels fast and professional.
Use enough spacing inside expanded panels so answers, lists, and product details are easy to read.
Do not hide important conversion information if users need it before clicking a button or making a decision.

Responsive Accordion Design Tips

Responsive accordion design matters because accordions are often used to simplify mobile pages. A long FAQ section, product information block, checkout help area, documentation menu, or dashboard settings page can feel much cleaner when the content is grouped into expandable sections.

On mobile screens, accordion rows should be easy to tap, headings should remain readable, icons should not disappear, and expanded content should not become too narrow. If the accordion includes columns, cards, images, pricing details, tables, or statistics, stack those elements vertically on smaller screens.

Desktop layout

Use wider accordion sections, side visuals, comparison blocks, pricing panels, and richer card layouts when there is enough space.

Tablet layout

Reduce complex columns, keep accordion titles readable, and make sure expanded content does not feel squeezed.

Mobile layout

Stack everything, increase tap areas, keep icons visible, and make sure every answer or content panel has comfortable spacing.

Use large tap targets so visitors can open accordion rows easily on mobile.
Avoid tiny icons that are hard to tap or difficult to see.
Stack complex content when an expanded panel contains cards, columns, tables, pricing items, or media blocks.
Keep headings short where possible so accordion labels do not wrap into confusing multi-line blocks.
Use readable line height because expanded accordion content often contains longer explanations.
Check resize behavior when you use dynamic max-height animation with JavaScript.

Common JavaScript Accordion Mistakes

Common JavaScript accordion mistakes usually happen when the component is built only for a quick demo instead of a real page. The accordion may work with short text, but then break when the content becomes longer, when the same component is used more than once, or when the layout changes on mobile.

The biggest problems are unclear clickable areas, missing active states, fixed panel heights, non-semantic markup, repeated class names, and JavaScript selectors that affect the wrong component. These issues are easy to avoid when you plan the accordion structure before writing the script.

Using unclear headers

Labels like “More info” are weak. Use clear labels such as “Shipping details”, “Warranty”, “Pricing FAQ”, or “Product specifications”.

Making only the icon clickable

The whole accordion header should open the panel, not just a small plus icon on the right side.

Hardcoding panel height

Fixed heights can break with long text, translated content, responsive wrapping, or dynamic content loaded later.

Using global selectors

Generic selectors can make multiple accordions conflict when several components are used on the same page.

Forgetting accessibility states

Update aria-expanded when an item opens or closes and keep trigger elements keyboard-friendly.

Repeating the same visual pattern

Different use cases need different layouts. A pricing accordion, product accordion, FAQ accordion, and dashboard accordion should not all look identical.

Do not remove focus outlines unless you replace them with a clear custom focus style.
Do not hide important buying information inside a closed panel if users need it before contacting you or buying.
Do not use hover-only accordions because they are weak for mobile and touch screens.
Do not use the same ID twice when copying accordion examples into one page.
Do not forget to test the accordion after adding real content, especially on mobile.

JavaScript Accordion FAQ

Here are common questions about JavaScript accordions for websites, FAQ sections, ecommerce pages, service pages, dashboards, documentation layouts, and responsive UI components.

What is a JavaScript accordion?

A JavaScript accordion is an interactive UI component that opens and closes content panels when users click a heading, button, question, or label. It is commonly used for FAQs, product details, pricing questions, support sections, and dashboards.

Where should I use an accordion on a website?

Use accordions where users need to scan many sections quickly, such as FAQ pages, product specifications, shipping details, pricing questions, help centers, service pages, documentation menus, course modules, and mobile filters.

Should only one accordion item open at a time?

It depends on the use case. One-open-at-a-time behavior is good for compact FAQ sections and pricing questions. Multi-open behavior is better for product details, dashboards, documentation, and settings panels where users may compare several sections.

Is JavaScript better than CSS for accordions?

JavaScript gives more control over active states, ARIA attributes, one-open-at-a-time behavior, dynamic heights, resize handling, nested accordions, and more advanced UI logic. CSS can be enough for very simple static accordions.

Can JavaScript accordions work well on mobile?

Yes. Accordions are especially useful on mobile because they reduce scrolling and keep long content organized. Use large tap targets, readable labels, clear icons, and stacked panel content for the best mobile experience.

Can I use these accordion examples in WordPress?

Yes. These examples use vanilla JavaScript, HTML, and CSS, so they can be pasted into a Gutenberg Custom HTML block. For a live website, repeated CSS and JavaScript should usually be moved into your theme or plugin files.

Conclusion

JavaScript accordions are practical UI components for modern websites because they make long content easier to scan, organize, and use. They are especially useful for FAQ sections, product details, pricing questions, support pages, documentation sections, mobile filters, dashboard settings, course modules, and content-heavy landing pages.

The best accordion examples are not only functional, but also visually clear. A professional accordion should have an obvious clickable header, a strong active state, smooth behavior, readable expanded content, mobile-friendly spacing, and JavaScript that does not conflict with other components on the same page.

Use these 30 JavaScript accordion examples as starting points for real website projects. You can adapt the styles, icons, layouts, colors, open behavior, and content structure for business websites, ecommerce stores, SaaS pages, WordPress sites, dashboards, help centers, and landing pages.
