## Overview

Use `.accordion` as the wrapper and `.accordion-item` for each section. Inside each item, use `.accordion-header`, `.accordion-button`, `.accordion-button-toggle`, and `.accordion-body`.

Accordion interaction uses Bootstrap Collapse. Add `data-bs-toggle="collapse"` and `data-bs-target="#panel-id"` to each `.accordion-button`, then use `.accordion-collapse.collapse` on the target panel. Use `.show` on the panel that should be open by default.

This preview shows the base structure with one expanded section.

<Example>
<div class="accordion" id="accordion-overview">
  <div class="accordion-item bg-surface">
    <h3 class="accordion-header">
      <button class="accordion-button" type="button" data-bs-toggle="collapse" data-bs-target="#overview-item-1" aria-expanded="true" aria-controls="overview-item-1"> Account details <span class="accordion-button-toggle"><Icon name="chevron-down" /></span> </button>
    </h3>
    <div id="overview-item-1" class="accordion-collapse collapse show" data-bs-parent="#accordion-overview">
      <div class="accordion-body">Update profile fields, contact details, and team role settings in this section.</div>
    </div>
  </div>
  <div class="accordion-item bg-surface">
    <h3 class="accordion-header">
      <button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#overview-item-2" aria-expanded="false" aria-controls="overview-item-2"> Security settings <span class="accordion-button-toggle"><Icon name="chevron-down" /></span> </button>
    </h3>
    <div id="overview-item-2" class="accordion-collapse collapse" data-bs-parent="#accordion-overview">
      <div class="accordion-body">Configure password policy, two-factor requirements, and active device sessions.</div>
    </div>
  </div>
  <div class="accordion-item bg-surface">
    <h3 class="accordion-header">
      <button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#overview-item-3" aria-expanded="false" aria-controls="overview-item-3"> Notification preferences <span class="accordion-button-toggle"><Icon name="chevron-down" /></span> </button>
    </h3>
    <div id="overview-item-3" class="accordion-collapse collapse" data-bs-parent="#accordion-overview">
      <div class="accordion-body"> Choose which updates to receive by email, browser push, and weekly digest. You can set separate rules for account alerts and product announcements. </div>
    </div>
  </div>
</div>
</Example>

## Variants

### Plus toggle icon

Use `.accordion-button-toggle-plus` to hide the first SVG path when expanded. This pattern is useful for plus-to-minus toggles.

<Example>
<div class="accordion" id="accordion-plus">
  <div class="accordion-item bg-surface">
    <h3 class="accordion-header">
      <button class="accordion-button" type="button" data-bs-toggle="collapse" data-bs-target="#plus-item-1" aria-expanded="true" aria-controls="plus-item-1"> Billing details <span class="accordion-button-toggle accordion-button-toggle-plus"> <Icon name="plus" /> </span> </button>
    </h3>
    <div id="plus-item-1" class="accordion-collapse collapse show" data-bs-parent="#accordion-plus">
      <div class="accordion-body">View invoices, payment method status, and tax details.</div>
    </div>
  </div>
</div>
</Example>

### With leading icon

Use `.accordion-button-icon` when a row needs a small icon before the label. The icon color uses the secondary token.

<Example>
<div class="accordion" id="accordion-icon">
  <div class="accordion-item bg-surface">
    <h3 class="accordion-header">
      <button class="accordion-button" type="button" data-bs-toggle="collapse" data-bs-target="#icon-item-1" aria-expanded="true" aria-controls="icon-item-1">
        <span class="accordion-button-icon"><Icon name="user" /></span> Team profile
        <span class="accordion-button-toggle"><Icon name="chevron-down" /></span>
      </button>
    </h3>
    <div id="icon-item-1" class="accordion-collapse collapse show" data-bs-parent="#accordion-icon">
      <div class="accordion-body">Manage member names, avatars, and workspace profile details.</div>
    </div>
  </div>
</div>
</Example>

### Flush accordion

Use `.accordion-flush` to remove side borders and border radius. The first and last items also remove top and bottom borders.

<Example>
<div class="accordion accordion-flush" id="accordion-flush">
  <div class="accordion-item bg-surface">
    <h3 class="accordion-header">
      <button class="accordion-button" type="button" data-bs-toggle="collapse" data-bs-target="#flush-item-1" aria-expanded="true" aria-controls="flush-item-1"> API access <span class="accordion-button-toggle"><Icon name="chevron-down" /></span> </button>
    </h3>
    <div id="flush-item-1" class="accordion-collapse collapse show" data-bs-parent="#accordion-flush">
      <div class="accordion-body">Generate tokens and control access scopes.</div>
    </div>
  </div>
  <div class="accordion-item bg-surface">
    <h3 class="accordion-header">
      <button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#flush-item-2" aria-expanded="false" aria-controls="flush-item-2"> Webhooks <span class="accordion-button-toggle"><Icon name="chevron-down" /></span> </button>
    </h3>
    <div id="flush-item-2" class="accordion-collapse collapse" data-bs-parent="#accordion-flush">
      <div class="accordion-body">Manage delivery URLs, retry policy, and event subscriptions.</div>
    </div>
  </div>
</div>
</Example>

## Examples

### Tab-like spacing

Use `.accordion-tabs` to add a gap between items and keep full borders around each item. This style works well for settings pages.

<Example>
<div class="accordion accordion-tabs" id="accordion-tabs">
  <div class="accordion-item bg-surface">
    <h3 class="accordion-header">
      <button class="accordion-button" type="button" data-bs-toggle="collapse" data-bs-target="#tabs-item-1" aria-expanded="true" aria-controls="tabs-item-1"> Workspace <span class="accordion-button-toggle"><Icon name="chevron-down" /></span> </button>
    </h3>
    <div id="tabs-item-1" class="accordion-collapse collapse show" data-bs-parent="#accordion-tabs">
      <div class="accordion-body">Configure workspace name, slug, and timezone.</div>
    </div>
  </div>
  <div class="accordion-item bg-surface">
    <h3 class="accordion-header">
      <button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#tabs-item-2" aria-expanded="false" aria-controls="tabs-item-2"> Notifications <span class="accordion-button-toggle"><Icon name="chevron-down" /></span> </button>
    </h3>
    <div id="tabs-item-2" class="accordion-collapse collapse" data-bs-parent="#accordion-tabs">
      <div class="accordion-body">Control email, push, and digest notification preferences.</div>
    </div>
  </div>
</div>
</Example>

### Inverted toggle position

Use `.accordion-inverted` to move the toggle to the start of the button row. This helps layouts where controls should appear before text.

<Example>
<div class="accordion accordion-inverted" id="accordion-inverted">
  <div class="accordion-item bg-surface">
    <h3 class="accordion-header">
      <button class="accordion-button" type="button" data-bs-toggle="collapse" data-bs-target="#inverted-item-1" aria-expanded="true" aria-controls="inverted-item-1"> Access policy <span class="accordion-button-toggle"><Icon name="chevron-down" /></span> </button>
    </h3>
    <div id="inverted-item-1" class="accordion-collapse collapse show" data-bs-parent="#accordion-inverted">
      <div class="accordion-body">Set default policy, invite flow, and sign-in restrictions.</div>
    </div>
  </div>
</div>
</Example>

## Accessibility

- Use a real `<button>` element for `.accordion-button`.
- Keep heading structure with `.accordion-header` so sections are easy to scan.
- Use `aria-expanded` and `aria-controls` on toggle buttons when wiring interactive behavior.
- Keep `data-bs-target` and panel `id` values in sync for every toggle.
- Keep visible focus styles. The header and button styles include focus handling.
- Add meaningful text labels, not only icons.

## SCSS variables

Use these SCSS variables to customize the accordion. The default values are:
