HI Musicmaster,
thanks for your reply,
I know i can assign a product to more than one category, but that is not what i'm looking for.
what i want is, i would like to create a custom final product from the different parts that are available in my store.
For example,
I have a outfit store, where i can Hat, Top, Pants & Shoes categories.
I would like to have a "Design your outfit" Tab, where the customer can chose different products from different categories and the final outfit will be presented to him/her so that they can see how it would look like.
