I reached the required result but the module still doesn't work, it always returns the same suppliers for all categories, that's wrong!, In fact if you enter some product sheets you notice that the supplier is different.
I leave the form active even if it doesn't work.
look in the left: https://www.farmamedic.it/vm/articoli-sanitari--xfubv.html
products with zero inventory
look: https://www.farmamedic.it/vm/articoli-sanitari--xfubv.html or other category, you will always see these categories, but it is not true because there are other photographs
the limit was set at 120m and is now set at 254M, but I still see all brands in all categories
It's showing brands now: https://www.farmamedic.it/megafilter-vm.html#sort=position&sortdir=desc&page=1
Kindly check.
the problem is that they are all brands, they cannot be all for all pages, only those related to the displayed products should be active, so for example if I click on https://www.farmamedic.it/vm/articoli- sanitari- 9007 / needles-and-syringes-8007.html I should only show the brands of those products, not all of them, because I don't need the brands that are not related to those products, do you agree?
