Submenu not shown (sharepoint)

[Lucas Denys]

I managed to install Radmenu in a Sharepoint Publishing site. I am not getting the submenu's though. Here is the code I use.

<telerik:RadMenu ID="RadMenu1"
                      runat="server"
                      DataSourceID="SiteMapDataSource1"
                      Skin="Simple" />
<PublishingNavigation:PortalSiteMapDataSource ID="SiteMapDataSource1"
                  Runat="server"
                  SiteMapProvider="GlobalNavSiteMapProvider"
                  EnableViewState="true"
                  StartFromCurrentNode="true"
                  StartingNodeOffset="0"
                  ShowStartingNode="false"
                  TreatStartingNodeAsCurrent="true"
                  TrimNonCurrentTypes="Heading"/> 

When I look into the code generated for the menu I see the submenu items are there. But nothing happens when I hover or click the top menu item.

What am I missing?.

What kind of ScriptManager are you using with this page? I've seen issues where if you're using a RadScriptManager switching to the regular ScriptManager takes care of the issue, and vice versa (ScriptManager to RadScriptManager). I recall reading a thread where once you do the switch you can actually switch right back once everything works.
