a customer orders a special product, I need for the order extra information.
Is it possible in some products, place user fields? (As shown in the registration)
What you can do is create custom fields of the table 'item' (Business edition). They will be displayed on the products page. If you don't want them on all the pages but only some pages, you will have to change a bit the code of a view, like explained on that post:
