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.

Example
Click the accordions below to expand/collapse the accordion content.
{{< example >}}
Accordion Item #1
This is the first item's accordion body. It is shown 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 .accordion-body, though the transition does limit overflow.
Accordion Item #2
This is the second item's accordion body. 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 .accordion-body, though the transition does limit overflow.
Accordion Item #3
This is the third item's accordion body. 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 .accordion-body, though the transition does limit overflow.

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.
{{< example class="bg-body-secondary" >}}
Accordion Item #1
Placeholder content for this accordion, which is intended to demonstrate the .accordion-flush class. This is the first item's accordion body.
Accordion Item #2
Placeholder content for this accordion, which is intended to demonstrate the .accordion-flush class. This is the second item's accordion body. Let's imagine this being filled with some actual content.
Accordion Item #3
Placeholder content for this accordion, which is intended to demonstrate the .accordion-flush class. This is the third item's accordion body. Nothing more exciting happening here in terms of content, but just filling up the space to make it look, at least at first glance, a bit more representative of how this would look in a real-world application.

Always open
Omit the data-bs-parent attribute on each .accordion-collapse to make accordion items stay open when another item is opened.

CSS
Variables
{{< added-in "5.2.0" >}}
As part of Bootstrap's evolving CSS variables approach, accordions now use local CSS variables on .accordion for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.
