How to add a collection of products?

Question

WordPress

I need to make an online store of building materials. The priority direction will be ceramic tiles. Tiles are always divided into collections.
It is necessary that the filter perceives not just one tile, but outputs a collection of tiles, i.e. I choose the size of the tile and the manufacturer in the filter and the collections drop out to me. For example, this site: www.kdv.ru/plitka-dlya-vannoy.html
I always drop out only the product, and not the collection in which it is contained.
