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
Generally, we recommend using a button with the data-bs-target
attribute. While not recommended from a semantic point of view, you can also use a link with the href
attribute (and a role="button"
). In both cases, the data-bs-toggle="collapse"
is required.
Some placeholder content for the collapse component. This panel is hidden by default but revealed when the user activates the relevant trigger.

<a class="btn btn-primary" data-bs-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample">Link with href<a>
<button class="btn btn-primary" type="button" data-bs-toggle="collapse" data-bs-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">Button with data-bs-target</button>
</p>
<div class="collapse" id="collapseExample">

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