Hi,
Filtering can only be applied to a products listing page and I can see that the filter module you have works fine on the products listing of each category you have.
I see that you configured the filter module to also appear on the categories listing page.
You can have it work on these pages too but in that case you need to either:
- change the "sub element filters" setting of the "products options" tab of your menu items to "all sub elements" instead of "direct sub elements" so that the products listing of all the products of the sub categories will display at the bottom when you access the categories listing page. That way, the filter module will refresh that products listing.
- activate the "force redirect" setting of the filter module and configure the "menu item id" setting above with the id of a menu item configured to display all your products. That way, when using the filter module it will redirect to that listing of all the products and filter the products based on what you selected. You could, with Advanced modules manager, have two different filter module, one for the categories listing pages, and one for the products listing pages so that it would only redirect with the one on the categories listing and stay on the current page for the products listings.
