All products from Group Shops in one domain

[GeorgeFree]

I need to have all products from all shops or group of shops to show in one domain.

 

I need to make at least one group shops all products from all shops were seen on one domain.

It is possible to set the basic administration if multistore enable, or need to create a module.

 

Schema:

GroupA > Shop1 > Category1 > Product1

GroupA > Shop2 > Category2 > Product2

GroupB > Shop3 > Category3 > Product3

 

In www.shoppingarena.eu see all categories/products from all Group or Shops.

In www.shoppingarena.eu/shop2 see categories/products from shop2

 

Thank you for advice.
