In the current version, seems that vendors can not define their own product groups with regards to the product configurations. The product groups have to be defined by the site administrators.
This would create some problems with the multi-vendor shopping cart. In this case, all vendors have to share the same product groups created by the site admin, and they have no way of creating their own product groups that can be used for their own product configurations.
Is there any way around this?
Thanks,
