Multiple questions in the 1 form


I am trying to create an order form in Smartsheets using the form function. I have created it so 1 item can be ordered but how do i set up this up so staff can order multiple items in the 1 form?

I thought maybe have a question, "would you like to add another item? if yes then i would use the same columns to trigger "i.e item, size" but i see these form fields available

I have a feeling this isn't possible.

Thank you
