-## Collapsible content
-
-Our collapse plugin allows you to use a `<button>` or `<a>` to toggle hidden content.
-
-{% example html %}
-<nav class="navbar navbar-light bg-faded">
-  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#exCollapsingNavbar" aria-controls="exCollapsingNavbar" aria-expanded="false" aria-label="Toggle navigation"></button>
-  <div class="collapse" id="exCollapsingNavbar">
-    <div class="bg-inverse text-muted p-1">
-      <h4>Collapsed content</h4>
-      <span class="text-muted">Toggleable via the navbar brand.</span>
-    </div>
-  </div>
-</nav>

-For more complex navbar patterns, like those used in Bootstrap v3, use the `.navbar-toggleable-*` classes in conjunction with the `.navbar-toggler`. These classes override our responsive utilities to show navigation only when content is meant to be shown.
