I apologize if this has already been suggested; the words involved are so generic that searching for them turns up too many results to go through.

I'm having a conceptual hurdle with the way line item types are selected. I need to collect different kinds of information when different types of product are added to a cart. Specifically, if someone orders a DVD, I don't need to know anything, but if they make a donation, I need to know in whose name the donation is being made, and if they're registering for an event, I need to know their meal preference, etc. I created line item types for each of these types of form and added the necessary fields to them, but in order to display the proper form, I have to set the line item type in the product reference field of the *content type*. This creates two problems for me: each time I want a new type of form to collect some kind of information, I have to also create another content type; and when creating a node to display products I have to be careful to select only products that are appropriate to the kind of line item that node will create.

What I'd like to propose instead is that the individual product -- or failing that, the product type -- should determine the line item type to be used with that product. That way you could display multiple different types of product in a single node (for example, register for an event *and* order the event T-shirt *and* contribute to the scholarship fund) and the Add to Cart form would change along with the product information. But more importantly, this would ensure that the proper information is always being collected for a given product regardless of where it is displayed.

Thank you for your consideration!
