This diagnosis is only relevant to UberMenu 2, not UberMenu 3
Background
The UberMenu Control Panel’s jQuery Enhancements option allows you to disable all javascript functionality of the menu to use a pure CSS menu if you prefer.
The Problem
If you disable jQuery Enhancements, you will lose all javascript functionality in the menu. This includes:
Animations
The slide and fade effects of the submenu are accomplished with jQuery. They will not appear with jQuery Enhancements disabled.
Maps
Google Maps are processed using javascript. Without it, the maps cannot be displayed.
HoverIntent & Click triggers
The top level menu item triggers are all powered by jQuery. If you disable jQuery Enhancements, the submenu will appear immediately upon hover – Click and HoverIntent triggers will have no effect.
Responsive Menu Toggle Button
The click event on the Responsive Menu Toggle button is controlled with jQuery. You need to enable jQuery Enhancements for Responsive sites.
Solution
Re-enable jQuery Enhancements in the UberMenu Control Panel > Basic Configuration > jQuery Animations & Auto-positioning > jQuery Enhanced
