I have a question regarding the hidden values (Options) in NetObjects ecommerce catalogs.

Do I have to use a combined list of all hidden variables (sizes, colors, styles, etc) or can each catalog have its own set of variables (Men's Jackets/Vests, Women's Jackets/Vests, Chaps, Lens Color for Eyewear, etc)?

Thank you in advance for any help you can provide.
