Hi
When you select the primary category within single product – in the XStore Options box at the bottom, on the single product page within the meta box it only shows this singular category – even though the product may belong in several categories.
The default behaviour is when you select a primary category, this is used within the url structure however the breadcrumbs stay intact and dont change between the other categories and also it shows all the categories on the single product page within the meta block that shows sku / category / tags etc.
This suggests your method is changing the structure slightly – however, my query is specifically:
How do we set the primary category and still show all categories that product sits in, within the meta block on the single product page please?
Thanks
