Hi
I want to add the post type “product_variation” to the create new post action.
How do i do that ?
How was your CPT added? If it was added via the normal WordPress way, it should appear in the listing.
product_variation is a native post type.
so i have not added it.
Is this really a Post Type? Or maybe a taxonomy? Can a WooCommerce user confirm that? 
Why need a confirm, when you just can add woocommerce with a variation and see in the SQL its creating a post type “product_variation” for it.
