I'm trying to filter a large amount of products using collections. I need a further filtering when navigating a menu, so I tried to use the "Filter with tags (optional)". It works fine and display the correct products in my collection page. In this page there is also a "Sort by" menù.
When I try to sort the products displayed in this way, the collection change, removing the "Filter with tags (optional)" used to display it. So I see all the products of the collection, without the applied filter.
There is a way to fix it without creating a dynamic sub-collection for every element of my menu?
