I'm pretty new to Umbraco but I need an answer from someone else more expert than me. I need to creare a sort of hierarchy, something like:
CATALOG > FIRST LEVEL (1...n) > SECOND LEVEL (1...n) > PRODUCT
From the basics I would create a documentType for the product (last item) and something else for each level. Would be enough another documentType? the use of tags might be useful?
