I am setting up a gifts shops. I have 2 questions: Can I set up multiple level categories (category > sub-category>sub-sub-category). I need at least 3 levels of categories. How do I do that? I need classification based on 2 criteria - categories according to shapes/types, and categories according to gift types(occasions, causes). How can I (rather can I) achieve this? The only solution I have in mind right now is to have my own site and redirect the people here. Any suggestions?
