Your extended menu is beautifully simple and easy to customize. We have been using it for five years at educationlaw.org, along with your excellent content slider, which I just renewed. I remember when we first installed the menu module we had some puzzling z-index conflicts with our template. This has happened again now that we updated to Joomla 3.72 and an all-new Joomlart template. What's happening is that the megamenu dropdowns slide underneath the ARI menu container. I've played with all kinds of z-index fixes but can't find the answer. You could probably scope it out right away, as you have in the past. The fix undoubtedly can be added to the module custom css window. If you have a few minutes, please see the problem here

That is the location where we are completing the Joomla update.
Thanks so much,
