Products are different from clothing to duffel bags and training. I need to show the size menu only on the products such as Clothing.
I have setup products table and in it ProductCategory:
1 | AG Clothing - this will have different Sizes - same price
2 | AG Clothing - no Sizes
3 | AG Training - no Sizes
There might be more categories in the future.
To answer your question the sizes will be applied only to 1 | AG Clothing.
