Hi,
We have a documentation which explains how to properly configure your categories listing menu there:
www.hikashop.com/support/documentation/6...html#categories_menu
Basically, you need to have a product listing module as "associated module" of your categories listing menu, otherwise, a categories listing menu is just a categories listing menu 
If you save the hikashop options of your categories listing menu without an associated module published, it will display you an error message with a link to create an associated module automatically in one click.
