Collapse
Bootstrap collapse
Toggle the visibility of content across your project with a few classes and our JavaScript plugins.
How it works
The collapse JavaScript plugin is used to show and hide content. Buttons or anchors are used as triggers that are
mapped to specific elements you toggle. Collapsing an element will animate the height
from it’s
current value to 0
.
Given how CSS handles animations, you cannot use padding
on a .collapse
element. Instead,
use the class as an
independent wrapping element.
Example
Click the buttons below to show and hide another element via class changes:
.collapse
hides content.collapsing
is applied during transitions.collapse.show
shows content
You can use a link with the href
attribute, or a button with the data-target
attribute.
In both cases, the data-toggle="collapse"
is required.
<!-- Collapse buttons -->

<a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" aria-expanded="false" aria-controls="collapseExample">

</a>
<button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample"
aria-expanded="false" aria-controls="collapseExample">
Button with data-target
</button>
</div>
<!-- / Collapse buttons -->

</div>
<!-- / Collapsible element -->
Multiple targets
A <button>
or <a>
can show and hide multiple elements by
referencing them with a JQuery selector in its href
or data-target
attribute. Multiple
<button>
or <a>
can show and hide an element if they each reference it with
their href
or data-target
attribute.

Accordion MDB Pro component
Using the card component, you can extend the default collapse behavior to create an accordion.

Accessibility
Be sure to add aria-expanded
to the control element. This attribute explicitly
conveys the current state of the collapsible element tied to the control to screen readers and similar assistive
technologies. If the collapsible element is closed by default, the attribute on the control element should have a
value of aria-expanded="false"
. If you’ve set the collapsible element to be open by default using the
show
class, set aria-expanded="true"
on the control instead. The plugin will
automatically toggle this attribute on the control based on whether or not the collapsible element has been opened
or closed (via JavaScript, or because the user triggered another control element also tied to the same collapsbile
element). If the control element’s HTML element is not a button (e.g., an <a>
or <div>
),
the attribute role="button" should be added to the element.
If your control element is targeting a single collapsible element – i.e. the data-target
attribute is
pointing to an id
selector – you should add the aria-controls
attribute to the control
element, containing the id
of the collapsible element. Modern screen readers and similar assistive
technologies make use of this attribute to provide users with additional shortcuts to navigate directly to the
collapsible element itself.
Usage
The collapse plugin utilizes a few classes to handle the heavy lifting:
.collapse
hides the content.collapse.show
shows the content.collapsing
is added when the transition starts, and removed when it finishes
Via data attributes
Just add data-toggle="collapse"
and a data-target
to the element to
automatically assign
control of a collapsible element. The data-target
attribute accepts a CSS selector to apply the
collapse to. Be sure to add the class collapse
to the collapsible element. If you’d like it to default
open, add the additional class in
.
To add accordion-like group management to a collapsible control, add the data attribute data-parent="#selector"
.
Refer to the demo to see this in action.
Via JavaScript
Enable manually with:
$('.collapse').collapse()
Options
Options can be passed via data attributes or JavaScript. For data attributes, append the
option name to
data-
, as in data-parent=""
.
Name | Type | Default | Description |
---|---|---|---|
parent | selector | false | If a selector is provided, then all collapsible elements under the specified parent will be closed
when this collapsible item is shown. (similar to traditional accordion behavior - this is dependent
on the panel class) |
toggle | boolean | true | Toggles the collapsible element on invocation |
Methods
Asynchronous methods and transitions
All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.
.collapse(options)
Activates your content as a collapsible element. Accepts an optional options object
.
$('#myCollapsible').collapse({
toggle: false
})
.collapse('toggle')
Toggles a collapsible element to shown or hidden.
.collapse('show')
Shows a collapsible element.
.collapse('hide')
Hides a collapsible element.
.collapse('dispose')
Destroys an element’s collapse.
Events
Bootstrap’s collapse class exposes a few events for hooking into collapse functionality.
Event Type | Description |
---|---|
show.bs.collapse | This event fires immediately when the show instance method is called. |
shown.bs.collapse | This event is fired when a collapse element has been made visible to the user (will wait for CSS transitions to complete). |
hide.bs.collapse |
This event is fired immediately when the hide method has been called.
|
hidden.bs.collapse | This event is fired when a collapse element has been hidden from the user (will wait for CSS transitions to complete). |
$('#myCollapsible').on('hidden.bs.collapse', function () {
// do something…
})
