I would like a user to be able to add a same product to multiple categories and sub-categories.
The purpose of this so the Navigation Menu Bar (categories) on the e-commerce website could be generated dynamically of categories and sub-categories.
In term of UX, I think it could increase findability of the products?
I am thinking using jsTree plugin on the backend to represent categories and subcategories. Could also allow products to be moved in bulk to different nodes of the tree. If this is bad UX what is alternative better approach?
