Nested-Categories-Management in MERN

1. Implement simple CRUD API to create product(name, price) & assign multiple categories to it

2. Category can be subcategory of other category & possibly N number of depth. check below example :

Category 1
    sub category 1 ( N number of depth)
        sub sub category ( N number of depth)
            sub sub sub category( N number of depth)
    Sub category 2 (N number of depth)
    Sub category 3 (N number of depth)
    Sub category 3 (N number of depth)


Category N (N number of depth)

3. Integrate API in React with List, add, edit, delete and assign categories.
