This code means that the header will have links like HOME | <Category Names> My problem is When I have a Sub Category, it is not displayed when I hover my mouse over the parent category. For example, say there is a Category MAIN with two subcategories SubA and SubB. I want SubA and SubB to be displayed when I hover my mouse over MAIN. How can do this? I tried this code This displays the subcategories SubA and SubB only when I click on MAIN and not when I hover on MAIN category. Any help on how to achieve this?
