I have a list which contains information that is heavily linked with info in another list. The most similar example that I've seen was where someone had a list of customers and then a total list of orders. What I would be attempting to do is add a webpart to the customer list's display form to show all the customer's orders in the other list (e.g., where customer name in order's = customer name in current item).
Is this possible to do dynamically without hindering performance too much (5000 items in other list)?
