Hi Jerome,
Thanks for your reply.
Just saw that the indentation was removed from the category structure in my first post. Have attached a screen dump to illustrate the story.
Then with respect to your answer.
We can imagine that, the vendor's root will be: ROOT/Products
At this moment, they would be able to set the "product category" they want.
That's correct,
they can then set the category they want for products. But the products should also be added to their own product listing: ROOT/Vendor/vendor name. Preferably automatically (and protected so they can't remove that link)
What do you mean by "vendor category group"? Can't find that term in the documentation. Where do I set this parameter? It's not part of Market Options > Categories Options, I guess.
About the plugin you mention, it doesn't exist at this moment? That's a pity since I'm not a coder...
The category structure I mention in my first post is crucial for my project. In my opinion it's one of the basics of a multi-vendor solution that vendors are able to share a category for their products while they have their own vendor category too.
Best regards
