When I have products in categories ( I have sub-categories in this category) I don't have sort by category just sort by price. I want to add sort by category with sort by price.
For example :
if i have computer category and i have laptop and Desktop sub-categories. I have many products also in computer category. When i am in computer catalog i wish to show also in navigation layer :
Sort by Category : Laptop(1) Desktop(2)
What is the problem ?
