Hello together I need a solution for the following problem. Normally, I filter into attributes and get the products that match the attribute value.
Example cellphone: Black, 64G Memory 16Mpixel Cam
Ok, that's easy.
But I also need the other way around. I am planning a shop with spices and spices. Because of food intolerances, I need an attribute to a reversal so that everything is displayed but not what I clicked in the filter. For example gluten.
How do I proceed there or does someone know a module? Can not be that I'm the first one of a filter to negate.
