<div class="rmSlide" style="left: 0px; top: 22px; width: 151px; height: 361px; overflow: hidden;">
<ul class="rmVertical rmGroup rmLevel1" style="left: 0px; top: -361px; display: block; visibility: visible;">
<li class="rmItem rmSeparator">
<a class="rmLink rmImageOnly" style="width: 151px;" href="#">
<span class="rmText"></span>
</a>
</li>
</ul>
</div>
By default, the embedded Telerik css sets the display: none; property for this class, therefore all my separators were hidden. I used the following code to fix the issue:
/* Added to fix hidden separators on the Radmenu ver. Q3 2013 */
.RadMenu .rmRootGroup a.rmImageOnly span.rmText
{
display: block !important;
}
A side note is that this does not seem to happen with the radMenus that are created without using a webservice. Telerik, this seems like a bug to me. Hope this helps anyone else with the same issue!
