Is there a way to create a dynamic order form that allows the customer to order an unlimited number of products?

I want to create an order form that does not have a finite number of products that the customer can order. The form will expand to let the customer order 10 products or 100 products. 

I'm sorry to say, but we don't have a feature that would allow you to do this unless you will just take the orders where no payment is involved. We have a few widgets that allow you to add an unlimited number of inputs sections.

If you will be integrating the form to Paypal, for example, then you will have to add the products and let customers choose it.
