Okay, after some investigation, it now appears that the menu will work with GP until I try to use UberMenu’s ‘row’ option. The test version works with it, but the theme version doesn’t.
You can see it in action via the link above. The ‘Discover Sayward’ menu is now working with the row removed. I added it to the Municipal Services section and it isn’t working. Any thoughts on where I might look to try and fix that?
