I don't have time to do this right now and it's urgent. I need a developer to take the NopCommerce 4.0 Admin site and change the categories widget in the Product page to allow to set a category and the sort value for that product within the category.
As you know, you can only set the category on the product.
Basically go back to how the old Admin did it.
You can do it right in the source code, does not have to be a plugin.
Please PM me with a price and when it can be done.
