I'm working on a project that mimics a product Catalog, all products belong to a Collection and they all have a Type and Attributes.
For instance, a shirt belongs to the Apparel Collection, so I created a Category called Collection and to which the Apparel Collection is a child.
Products have types, for instance a shirt is a type of product, a hat is another type of product, ideally I can group all the products of the same type together and filter accordingly, I'm using Tags for this, a tag 'shirt', another one 'jeans', etc.
My problem resides on the fact that Products can also have attributes or characteristics, for instance a shirt can be white or screen printed, a pair of jeans could have a particular style or color.
I want to filter my posts by Collection (Categories), Types (Tags) and Attributes (??) individually, which I can do up to Attributes, since I ran out of taxonomy?
What is the best way to tackle this issue? Is it a custom post type for Types, since they can be enumerated and move the attributes to tags?
Any help is greatly appreciated.
Thanks, Leo
