How can I do and-and filter when filtering with layered navigation?
When I filter attributes (
size = 50, color = red), the result returns a configurable product when some of this child products have one of the attributes (
child 1 = 50, child 2 = red), but I need to return when one of the simple products has these 2 filtered attribute (
child 1 = 50, child 1 = red)
