Example
Click the buttons below to show and hide another element via class changes:
Some placeholder content for the collapse component. This panel is hidden by default but revealed when the user activates the relevant trigger.
Code Example
<p> <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"> <div class="card card-body"> Some placeholder content for the collapse component. This panel is hidden by default but revealed when the user activates the relevant trigger. </div> </div>
Horizontal
The collapse plugin also supports horizontal collapsing. Add the .collapse-horizontal modifier class to transition the width instead of height and set a width on the immediate child element.
This is some placeholder content for a horizontal collapse. It's hidden by default and shown when triggered.
Code Example
<p> <button class="btn btn-primary" type="button" data-bs-toggle="collapse" data-bs-target="#collapseWidthExample" aria-expanded="false" aria-controls="collapseWidthExample"> Toggle width collapse </button> </p> <div style="min-height: 120px;"> <div class="collapse collapse-horizontal" id="collapseWidthExample"> <div class="card card-body" style="width: 300px;"> This is some placeholder content for a horizontal collapse. It's hidden by default and shown when triggered. </div> </div> </div>
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
Some placeholder content for the first collapse component of this multi-collapse example. This panel is hidden by default but revealed when the user activates the relevant trigger.
Some placeholder content for the second collapse component of this multi-collapse example. This panel is hidden by default but revealed when the user activates the relevant trigger.
