I am trying to: find out if it is possible to group Woocommerce products using a custom post type where the Woocommerce product is a child of my product group post.
I understand that the Woocommerce group product facility (taxonomy based) does most of what I want to do but I will have several thousand "groups" and I want to include additional fields and functionality at a group level.
My store will be based on product group types only, which will be hierarchical.
Eg. Stationery > Diaries > A5 page to view
Under the above group there would be individual products (all A5 page to view diaries).
I would create templates for Woocommerce products and for the Product Groups.
I have 25,000 products (Woocommerce products) and these will be grouped so that there will be 5000 product groups.
