Accordion

Vue Accordion component

Responsive accordion built with the latest Bootstrap 5 and Vue 3. Accordion is a vertically collapsing element to show and hide content via class changes.

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

How it works

The accordion uses collapse internally to make it collapsible.

Basic example

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

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 MDBAccordionItem, though the transition does limit overflow.

Borderless

Add .accordion-borderless to remove all the borders and add a background color to the active item.

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.

CSS variables

As part of MDB’s evolving CSS variables approach, accordion now uses 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.
