Filtering products in subcategories does not work

Hi,

On the page /2d-assets/characters before using any filter, there are no products shown :

So even if you select filters... filtering something that isn't there cannot produce any result.
You would have to have products displayed there before using the filters if you want the filters to display something when you use them.

Regarding the homepage, the menu item is not of a HikaShop category/product listing there.
So when you use a filter you can see that the URL changes to /component/hikashop/product/listing?Itemid=144 because it redirects there when the current menu item is not already a listing of categories/products.
So that means that you have entered 144 in the menu item id setting of the filter module.
However, that menu item is not a HikaShop category/product listing.
So you need to fix that setting of your filter module. In there, you should enter the id of a menu item which by default lists all your products. That way, when you use a filter of the module on a page which isn't already listing categories/products, it will filter these produts of the menu item.
Alternatively, you could also configure your homepage menu item to display all the products of the shop and it would work too. Because right now, your homepage looks pretty empty:

Hi,

If you want to always search through all the products when you use a fitler of the filter module, you need two things:
1. have the "force redirect" setting activated in the filter module
2. configure the id of a menu item which by default displays all the products in the "menu" setting of the filter module.

The filter system can work like you expect it to work, but please understand that others might have other needs and being able to apply the filter only on the products of the current listing is something actually used by a lot of merchants.
That's why you can actually configure the module to work both ways.
