I have a fairly large menu with top and sub menu items.
I want to hide sub-menu items when the specific category is not selected but show all the sub categories of the active category.
My menu has 3 categories
1. Arts & Entertainment
3. E-Business & E-Marketing
Under Arts & Entertainment - I have Art, Body Art & Dance. When I click on the "Arts & Entertainment" link it must open and show the sub menu, for example:
Arts & Entertainment
E-Business & E-Marketing
You can do something similar by using the accordion element on your page as shown in the video above...
