## Usage
Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the `.open` class on the parent list item.
On mobile devices, opening a dropdown adds a `.dropdown-backdrop` as a tap area for closing dropdown menus when tapping outside the menu, a requirement for proper iOS support. **This means that switching from an open dropdown menu to a different dropdown menu requires an extra tap on mobile.**
Note: The `data-toggle="dropdown"` attribute is relied on for closing dropdown menus at an application level, so it's a good idea to always use it.
### Via data attributes
Add `data-toggle="dropdown"` to a link or button to toggle a dropdown.
<h3>Via data attributes</h3>
<p>Add <code>data-toggle="dropdown"</code> to a link or button to toggle a dropdown.</p>
