I know that I can filter by the characteristics, but...
Is there a way to filter the products by the given attributes of the products?
For example:
You have a product: P01 and different sub_products by their color (P01-1 and P01-2)
The attribute is 'Color', and the Attribute values are 'Red' and 'Orange'
Is there a way to display only those products, that has Red color and the stock > 0 ???
