My site is a company formation site, where users go to place orders for a variety of different entities. I have been creating attributes to define several things about the customers' proposed companies, but I need help on one thing.

If a customer is looking to order a Limited Liability Partnership, I need to know the names of the partners in the partnership. How do I allow the customer to add additional fields when there are more partners than spaces to insert their names?

I would appreciate any help of this wonderful community.
Thank you.
