I would like to be able to create a function or link for the following scenario. Certain products fall into a Hardware category and others fall into a Software category. Each of those categories have subcategories such as Windows Software, Mac Sofware, Linux Software, etc (There are about 10-15 subcategories). I would like to be able to show these subcategories on the Software level page in a list with the software that falls under each subcategory.
Any ideas how? or any references?
