Question

1C-Bitrix

Hello!
There is such a question, is it possible to somehow make a smart filter at the root of the catalog where the 1st level of sections where products are not displayed.
For example, I chose the right size, the right color, clicked on the filter button and the products appeared exactly where these parameters are? (Aspro max solution)

I made it a smart filter component, there are parameters in the filter, but when you click on filter, the products do not appear.

Maybe someone did something similar in aspro max?

Answer 2

Maybe someone did something similar, share the solution.
