I'm trying out UberMenu but ran into problems because it wanted to know which menu I wanted to use as the mega menu. The only problem was that my custom sidebar menu was not showing (my theme only had two locations registered: main which is horizontal and the footer). So I used the instructions from this page to register the sidebar as another menu location.
Now I have a random list of menu items appearing on my website in the sidebar. By random I mean a mix of the Main custom menu items and the Sidebar custom menu items.
While under the Appearances > Menu tab, I try to select over to the Sidebar custom menu. Suddenly the entire drag and drop option disappears. I have to go deactivate Ubermenu to get it to show up again.
I've tried the Jquery mega menu option but frankly it's ugly. Please help!
