<h2 id="dropdowns-usage">Usage</h2>
|
|
<p>Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the <code>.open</code> class on the parent list item.</p>
|
|
<p>On mobile devices, opening a dropdown adds a <code>.dropdown-backdrop</code> as a tap area for closing dropdown menus when tapping outside the menu, a requirement for proper iOS support. <strong class="text-danger">This means that switching from an open dropdown menu to a different dropdown menu requires an extra tap on mobile.</strong></p>
|
|
<p>Note: The <code>data-toggle="dropdown"</code> attribute is relied on for closing dropdown menus at an application level, so it's a good idea to always use it.</p>
|
|
|
|
<h3>Via data attributes</h3>
|
|
<p>Add <code>data-toggle="dropdown"</code> to a link or button to toggle a dropdown.</p>
|
|
{% highlight html %}
|
|
<div class="dropdown">
|
|
<button id="dLabel" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
|
|
Dropdown trigger
|
|
<span class="caret"></span>
|
|
</button>
|
|
<ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
|
|
...
|
|
</ul>
|
|
</div>
|
|
{% endhighlight %}
|
|
<p>To keep URLs intact with link buttons, use the <code>data-target</code> attribute instead of <code>href="#"</code>.</p>
|
|
{% highlight html %}
|
|
<div class="dropdown">
|
|
<a id="dLabel" data-target="#" href="http://example.com" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
|
|
Dropdown trigger
|
|
<span class="caret"></span>
|
|
</a>
|
|
|
|
<ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
|
|
...
|
|
</ul>
|
|
</div>
|
|
{% endhighlight %}
|
|
|
|
<h3>Via JavaScript</h3>
|
|
<p>Call the dropdowns via JavaScript:</p>
|
|
{% highlight js %}
|
|
$('.dropdown-toggle').dropdown()
|
|
{% endhighlight %}
|
|
<div class="bs-callout bs-callout-info">
|
|
<h4><code>data-toggle="dropdown"</code> still required</h4>
|
|
<p>Regardless of whether you call your dropdown via JavaScript or instead use the data-api, <code>data-toggle="dropdown"</code> is always required to be present on the dropdown's trigger element.</p>
|
|
</div>
|
|
|
|
<h3>Options</h3>
|
|
<p><em>None</em></p>
|
|
|
|
<h3>Methods</h3>
|
|
<h4>$().dropdown('toggle')</h4>
|
|
<p>Toggles the dropdown menu of a given navbar or tabbed navigation.</p>
|
|
|
|
<h3>Events</h3>
|
|
<p>All dropdown events are fired at the <code>.dropdown-menu</code>'s parent element.</p>
