First, I don't know anything about programming and I'm not interested in going through that curve or talking about things that don't meet my specific request. I just want to solve this problem in particular. Thanks.
I see that I can only add input fields if I open the database option, horrible, but there is no other option. I thought I could connect a tag from the drop-down list to a category store, so if this entry field is located on the store page, when choosing the category tag the gallery is reordered and shows me only that category .
I don't want to use the filters because they affect the design of the page, instead a drop-down entry field can be placed anywhere on the store. Someone can help?
