Adding Attribute Sets to the Woo Product Catalog

Hello,

I need to add additional attributes to the Product Catalog filters (Click the “Show Filters” button. Currently, I have 2 category sets showing on top (“Product Type”, and “Application Type”). Also, I have 1 Attribute set showing (“Application Series”).

However, I would also like to add a few more attribute sets (“Application Weight”, “Main Material”, “Interior/Exterior”, and “Shape & Characteristics”)

Any advice on where to start would be greatly appreciated.

Thanks!
Craig
