[TYPO3-commerce] Commerce categories

[Koller Michel]

Hello

It's my first time to work with commerce

I have a Structure like this:

Categorie1
    undercategorie-x
    undercategorie-y
Categorie2
    undercategorie-x
    undercategorie-y
etc

The Categories have all the same undercategorie's Structure.

The Solution i want have a Site that i can look all undercategorie-x (from 
cat 1 AND cat2)
and a Site where i can see all undercategorie-y (from cat 1 AND cat2)
and a Site where i can see all categorie1 (from undercategorie-x  AND from 
undercategorie-y)

Is this Strukture correct? or i am on the wrong Way?

Thanks for any help
