Accordion
Bootstrap 5 Accordion component
Responsive accordion built with the latest Bootstrap 5. 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. To render an accordion that’s expanded, add the .show
class
on the .accordion-collapse
.
*
*
UMD autoinits are enabled
by default. This means that you don't need to initialize
the component manually. However if you are using MDBootstrap ES format then you should pass
the required components to the initMDB
method.
Basic example
Click the accordions below to expand/collapse the accordion content.

Accordion - API
Import
Importing components depends on how your application works. If you intend to use the MDBootstrap ES
format, you must
first import the component and then initialize it with the initMDB
method. If you are going to use the UMD
format,
just import the mdb-ui-kit
package.
import { Collapse, initMDB } from "mdb-ui-kit";
initMDB({ Collapse });
import "mdb-ui-kit"
Usage
Via data attributes
Using the Accordion component doesn't require any additional JavaScript code - simply add
data-mdb-collapse-init
attribute to
every .accordion-button
and use other data attributes to set all options.
For ES
format, you must first import and call the initMDB
method.

Via JavaScript
const element = document.querySelector('.accordion')
const instance = new Collapse(element)
const element = document.querySelector('.accordion')
const instance = new mdb.Collapse(element)
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.
