The add-on allows you to create a tree of dependent filters. It is very convenient for the customer. Step by step, the customer chooses the characteristics of the product, without losing sight of anything. Multi-level filters - the shortest way for the customer to the product.
Add-on's settings are very simple. The logic for setting filters is the same as for a regular CS-Cart, only the ability to select a parent filter is added. On the storefront when you click on the parent filter appears child.
