In your example, I can change it to allow a drop-down menu in the "channel" menu in IE with a few minor changes to your fiddle: http://jsfiddle.net/amelvin/XxSTF/ - but you will need to rebuild the style.
I wonder if the boot block is confused using the dropdown menus.
<span class="dropdown" id="filter-add"> <a href="#filter-add" id="addFilter" class="dropdown-toggle" data-toggle="dropdown" > More </a> <ul id="Channels" class="nav nav-pills"> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown">Channel</a> <ul class="dropdown-menu"> <li> <select> <option value="1" >LIst Item 1</option> <option value="2" >LIst Item 2</option> <option value="3" >LIst Item 3</option> <option value="4" >LIst Item 4</option> <option value="5" >LIst Item 5</option> <option value="6" >LIst Item 6</option> </select> </li> </ul> </li> <li><a>Cancel</a></li> </ul> </span> $('.dropdown select').click(function(e) { e.stopPropagation(); }); $("#Channels").hide(); $("#addFilter").click(function() { $("#Channels").show(); });
