I'm a little confused on how to create the filtering and I don't know if this comes with cs-cart or it has to be purchased.
Say they are 3 different sizes but each comes with a list of sizes within it. So for example:
Medium: 5x8, 7x10
Room: 8x10, 9x12, 10x14
Small: 2x3, 4x5, 5x6
All products are in different sizes but if someone clicks on the small all of the 2x3, 4x5, and 5x6 show up.
The filter option in cs-cart gives the options for price, in stock, and free shipping. I can try options or features but can I add a filter for products on the storefront by those?
