+description: Build vertically collapsing accordions in combination with our Collapse JavaScript plugin.
+group: components
+aliases:
+ - "/components/"
+ - "/docs/5.0/components/"
+toc: true
+---
+
+## How it works
+
+The accordion uses [collapse]({{< docsref "/components/collapse" >}}) internally to make it collapsible. To render an accordion that's expanded, add the `.open` class on the `.accordion`.
+
+{{< callout info >}}
+{{< partial "callout-info-prefersreducedmotion.md" >}}
+{{< /callout >}}
+
+## Example
+
+Click the accordions below to expand/collapse the accordion content.
+
+{{< example >}}
+<div class="accordion" id="accordionExample">
+ <div class="accordion-item">
+ <h2 class="accordion-header" id="headingOne">
+ <button class="accordion-button" type="button" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
+ Accordion Item #1
+ </button>
+ </h2>
+ <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">
+ <div class="accordion-body">
+ <strong>This is the first item's accordion body.</strong> It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables. It's also worth noting that just about any HTML can go within the <code>.accordion-body</code>, though the transition does limit overflow.
+ </div>
+ </div>
+ </div>
+ <div class="accordion-item">
+ <h2 class="accordion-header" id="headingTwo">
+ <button class="accordion-button collapsed" type="button" data-toggle="collapse" data-target="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">
+ Accordion Item #2
+ </button>
+ </h2>
+ <div id="collapseTwo" class="collapse" aria-labelledby="headingTwo" data-parent="#accordionExample">
+ <div class="accordion-body">
+ <strong>This is the second item's accordion body.</strong> It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element.

+ <div class="accordion-body">
+ <strong>This is the third item's accordion body.</strong> It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element.

+
+### Flush
+
+Add `.accordion-flush` to remove the default `background-color`, some borders, and some rounded corners to render accordions edge-to-edge with their parent container.

-Using the [card]({{< docsref "/components/card" >}}) component, you can extend the default collapse behavior to create an accordion. To properly achieve the accordion style, be sure to use `.accordion` as a wrapper.

## Accessibility
Be sure to add `aria-expanded` to the control element. This attribute explicitly conveys the current state of the collapsible element tied to the control to screen readers and similar assistive technologies. If the collapsible element is closed by default, the attribute on the control element should have a value of `aria-expanded="false"`. If you've set the collapsible element to be open by default using the `show` class, set `aria-expanded="true"` on the control instead. The plugin will automatically toggle this attribute on the control based on whether or not the collapsible element has been opened or closed (via JavaScript, or because the user triggered another control element also tied to the same collapsible element). If the control element's HTML element is not a button (e.g., an `<a>` or `<div>`), the attribute `role="button"` should be added to the element.
