I'm using bootstrap and would like to know how do I work with multi-level dropdown menu?
<div class="btn-group">
<a href="index.php" class="btn btn-warning">Item1</a>
<a href="paroquias.php" class="btn btn-warning">Item2</a>
<div class="dropdown btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-expanded="true">
Menu-Dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu btn btn-warning" role="menu" aria-labelledby="dropdownMenu1">
<li><a href="#" class="btn btn-warning">Menu</a></li>
<li class="divider"></li>
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
SubMenu1
<span class="caret"></span>
</button>
<li><a href="#">SubMenu2</a></li>
<li><a href="#">SubMenu3</a></li>
</ul>
</div>
