Hi,
HikaShop (2.3.2) does not allow the display (and the application) of the filters outside the product/category listing menus.
If we want to activate the filters on the vendor page, we need to modify HikaShop (to hack it) so I don't think it's the good idea ; the best will be to propose a real patch to allow HikaMarket to ask for the HikaShop filters ; to bypass the restriction.
