My menu 1 (horizontal menu with div id="nav") is now showing sub-level pages after I dragged top level pages under home page to make them sub-level.
Make sure you have republished the pages that you have moved and you have refreshed the cache ( visit yoursite.com?flush=1 ) if you have done both of those how is your menu defined in the template? eg have you got a <% control Menu(1) %> with a <% control Children %> inside it?
I didn't have the <% control Children %>... Since this is my 1st post and reply, I appreciate your promptness in helping me with this issue. SilverStripe has almost converted me from Joomla! Too many developers do not understand how important it is to make the interface for average users easy. You guys get it; however, I can't wait until later versions when you make it easier for us Web Developers:)
