I'm utilizing bootstrap to create a horizontal menu in HTML
<div class="btn-group"">
<div class="btn-group">
<button type="button" data-toggle="dropdown" class="btn btn-inverse dropdown-toggle>About Us<span class="caret"></span></button>
<ul class="dropdown-menu">
<li><a href="/a/">Submenu 1</a></li>
<li><a href="/b/">Submenu 2</a></li>
</ul>
</div>
</div>
It currently triggers on click, is there a way to modify this code to display submenu items when hovering instead of clicking?
