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.

Required ES init: 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.

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.

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.

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.

With icons

You can easily add icons to the header of the accordion. Read icons docs to see all the available icons.

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.

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.

Show code Edit in sandbox

javascript
umd

        
            
          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.

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.
