mod_hikashop_filter

I cannot get this to work properly. I have read the documentation which says:

And Finally, you can also display your filters as a module by configuring the HikaShop Filter module via the joomla module manager. In your filter module, don't forget to set the id of a HikaShop category listing menu (you need to create that menu beforehand) in the menu option. If you use categories, the menu won't display products but only the categories on the search results page by default. You will have to change the "sub elements filter" option of the associated module of your category listing menu to "all sub elements" so that it displays all the products and not only the products directly linked to the parent category of your menu. And if you want to hide the category listing on that page, you will be able to do that by adding such CSS line (replace the X by the id of your menu) in the front end CSS file that you can edit via the Display tab of the configuration:

#hikashop_category_information_menu_X .hikashop_subcategories{ display:none; }
