I think I found a small bug in the shop
But when you create the item into different groups where there must be logged in to purchase the individual items, so it works fine ..
But I search for an item, I get the whole catalog and suddenly it can be purchased by anyone. I've made so that when a person logs in and has group 1, they get a shop for the menu, the same with group 2 and group 3
Can you in any way close it, so the customer is not logged in can not put the item to Cart?
Or simply just do something in search so that only group items that appear?
