I've got the module installed for the menu and it's great - lets me right click on drop downs, creates easy urls, etc. But I was messing around with the default DNN5 skin trying to do the drop down effects, and put in the following code to no effect (beyond moving to a DRR menu):
<div class="menu_style">
<dnn:NAV runat="server" id="dnnNAV" ProviderName="DDRMenuNavigationProvider" IndicateChildren="false" ControlOrientation="Horizontal" CSSControl="mainMenu" />
<CustomAttributes>
<dnn:CustomAttribute Name="effect" Value="puff"/>
<dnn:CustomAttribute Name="effectOptions" Value="{percent:200}"/>
<dnn:CustomAttribute Name="effectSpeed" Value="slow"/>
</CustomAttributes>
</dnn:nav>
JQuery is enabled in control settings - version hosted on Google - I'm sure I'm missing something dumb fairly new to jquery usage in DNN.
