# Collapse

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

## Example

Link with href

Some placeholder content for the collapse component. This panel is hidden by default but revealed when the user activates the relevant trigger.

    <!--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

This is some placeholder content for a horizontal collapse. It's hidden by default and shown when triggered.

     <!--Horizontal -->

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

        </button>
      </p>
      <div>
        <div class="collapse collapse-horizontal" id="collapseWidthExample">
          <div class="card card-body" style="width: 300px;">
