Hi,
In the HikaMarket tutorial, there is a part which explain some details about the vendor categories.
www.hikashop.com/support/documentation/1...html#tuto_first_conf
You can configure HikaMarket to restrict your vendors in a specific category so they can't place their products anywhere in your store. It is called the "vendor root category".
By removing this restriction, at this moment your vendors would be able to select any existing category.
But you can also specify a category, which won't be the "vendor home", but another category depending on the vendor and what kind of product he will sell.
The vendor home is a category created by HikaMarket (if you activate it in the configuration). You have the specify the category which will receive this vendor categories. So by default they will be create in a precise place.
Like any other category, you can move a vendor category by changing is parent category. So you organize like you want your vendors in your category tree.
By setting the "vendor root category" to the "vendor home", the vendor will be restricted to his vendor category, wherever you place it.
If there is something you don't understand, if you think there is a missing feature. Don't hesitate to ask me.
I hope my answer will help you to understand the HikaMarket category management.
I don't visualize right what you want to do, that's why I am thinking that it might be something missing (and we will be happy to continue to improve HikaMarket).
Regards,
