Hi,
When you have categories in the main area and you don't want that, you can add a display:none; CSS property on the element around the categories there.
If you could give a link to that page, I could give the precise CSS code to use.
Otherwise, I can only give you a link to the standard documentation about how to add CSS to HikaShop:
www.hikashop.com/support/support/documen...ize-the-display.html
Regarding the categories listing module, if you don't get the products when you click on a link of the module, it either means that you didn't select a categories listing menu in the "menu" option of the module, or that you did but that this menu item is not configured properly. In that case, we would need a screenshot of the settings of the menu item (that you can display by editing it via the menu Display>Content menus).
