Vue

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. 
<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>

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
