Navigation hover animation not working

The Navigation hover animations (as per this link - https://www.balbooa.com/showcase-template/gridbox/navigation-hover-animation-demo) seem to work well on Pages in Gridbox.

However, when I create an app (from within Zero App) and place a menu item with navigation hover animation, it does not work. I placed all CSS & Javascript correctly, but it just does not work on those pages. See sample link - https://www.televisionjamaica.com/smile-jamaica/smile-jamaica-2

How can I correct?
