ClickToOpen="true" not working

[Regula]

Hi,

I'm using the property  ClickToOpen="true" in the RadMenu, but it is not working. When I click, the menu doesn't open. When not using the ClickToOpen="true"  the menu works correctly. I checked the browser console and no error is logged. 

 

<telerik:RadMenu RenderMode="Lightweight" runat="server" ID="RadMenu4" Style="z-index: 7" EnableRoundedCorners="true" ShowToggleHandle="true" EnableImagePreloading="true"
                       EnableShadows="true" EnableTextHTMLEncoding="true" CausesValidation="False" OnItemDataBound="RadMenu4_ItemDataBound" ClickToOpen="true">
                       <DataBindings>
                           <telerik:RadMenuItemBinding DataMember="Menu"
                               TextField="PageTitle"
                               NavigateUrlField="ControllerURL" />
                       </DataBindings>
                   </telerik:RadMenu>
