Mark Otto 466d36e541 Redo all our callouts with the custom callout plugin
- Replaces manual use of .bd-callout with {% callout [type] %}
- Rearranged some callouts for proximity to others
- Turned long lists of callouts--like those on tooltips, plugings, etc--into a list because holy shit that's overwhelming

Use any button to trigger a dropdown menu by placing it within a `.btn-group` and providing the proper dropdown menu markup.
{% callout danger %}
#### Plugin dependency
Button dropdowns require the [dropdown plugin](../javascript/#dropdowns) to be included in your version of Bootstrap.
{% endcallout %}
### Single button dropdowns
Turn a button into a dropdown toggle with some basic markup changes.
<div class="bd-example">
<div class="btn-group">
<button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-expanded="false">Default</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
<div class="btn-group">
<button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown" aria-expanded="false">Primary</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
<div class="btn-group">
<button type="button" class="btn btn-success dropdown-toggle" data-toggle="dropdown" aria-expanded="false">Success</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
<div class="btn-group">
<button type="button" class="btn btn-info dropdown-toggle" data-toggle="dropdown" aria-expanded="false">Info</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
<div class="btn-group">
<button type="button" class="btn btn-warning dropdown-toggle" data-toggle="dropdown" aria-expanded="false">Warning</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
<div class="btn-group">
<button type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown" aria-expanded="false">Danger</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
</div>
{% highlight html %}
<!-- Single button -->
<div class="btn-group">
<button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
Action
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
{% endhighlight %}
### Split button dropdowns
Similarly, create split button dropdowns with the same markup changes, only with a separate button.
<div class="bd-example">
<div class="btn-group">
<button type="button" class="btn btn-secondary">Default</button>
<button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
<div class="btn-group">
<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
<div class="btn-group">
<button type="button" class="btn btn-success">Success</button>
<button type="button" class="btn btn-success dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
<div class="btn-group">
<button type="button" class="btn btn-info">Info</button>
<button type="button" class="btn btn-info dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
<div class="btn-group">
<button type="button" class="btn btn-warning">Warning</button>
<button type="button" class="btn btn-warning dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
<div class="btn-group">
<button type="button" class="btn btn-danger">Danger</button>
<button type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>

<!-- Split button -->
<div class="btn-group">
<button type="button" class="btn btn-danger">Action</button>
<button type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
<span class="sr-only">Toggle Dropdown</span>

<ul class="dropdown-menu" role="menu">

<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
{% endhighlight %}
### Sizing

<div class="bd-example">

</button>
<ul class="dropdown-menu" role="menu">

<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
</div><!-- /btn-toolbar -->

<div class="bd-example">
<div class="btn-toolbar" role="toolbar">
<div class="btn-group dropup">
<button type="button" class="btn btn-secondary">Dropup</button>
<button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-expanded="false">

</div>
{% highlight html %}
<div class="btn-group dropup">
<button type="button" class="btn btn-secondary">Dropup</button>
<button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu" role="menu">
<!-- Dropdown menu links -->
</ul>
</div>
