Sorry, the url will not display correctly in my post above. Here is my post from the other thread:
Go to Modules – Site Modules. Verify that JA Trans Menu V20 is published. For this example I am using TransMenu as my main menu so in Site Modules find Main Menu and unpublish it. Now click on Main Menu and make a note of the settings for position, menu name, and menu style. Cancel. Now back in Site Modules click on JA Trans Menu V20. Enter the same settings as your main menu for position and menu style. Now select mainmenu as the menu name setting for TransMenu and save your settings.
In order to see the TransMenu dropdown menu you will have to add a submenu item. Go to Menu – Main Menu (even though it is no longer published TransMenu will pull the settings from here). Set up a new menu item and link it to an existing menu item so it will be a submenu item. I use a link (URL) for a quick test. Save the new menu item and check your sites home page. The new item should show up.
Hope this helps!
