Collapse

Toggle the visibility of content across your project with a few classes and our JavaScript plugins.

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.

Link with href

Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident.

<p>
  <a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
    Link with href
  </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>
</p>
<div class="collapse" id="collapseExample">
  <div class="card card-body">
    Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident.
  </div>
</div>

Accordion example

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

You can also create accordions with custom markup. Add the data-children attribute and specify a set of sibling elements to toggle (e.g., .item). Then, use the same attributes and classes as shown above for connecting toggles to their associated content.

Toggle item

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed pretium lorem non vestibulum scelerisque. Proin a vestibulum sem, eget tristique massa. Aliquam lacinia rhoncus nibh quis ornare.

Toggle item 2

Donec at ipsum dignissim, rutrum turpis scelerisque, tristique lectus. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vivamus nec dui turpis. Orci varius natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

<div id="exampleAccordion" data-children=".item">
  <div class="item">
    <a data-toggle="collapse" data-parent="#exampleAccordion" href="#exampleAccordion1" aria-expanded="true" aria-controls="exampleAccordion1">
