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

  <button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">

  </div>
</div>

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 example

Using the card component, you can extend the default collapse behavior to create an accordion. To properly achieve the accordion style, be sure to use .accordion as a wrapper.
