Accordion

Build vertically collapsing accordions in combination with our Collapse JavaScript plugin.

Official Bootstrap 5 Accordion.

Example

Click the accordions below to expand/collapse the accordion content.

This is the first 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.

Placeholder content for this accordion, which is intended to demonstrate the .accordion-flush class. This is the first item's accordion body.

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.

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.
