In an event we are selling shirts, and would like to allow registrants to purchase as many of them as we want (this is just one example) and as such we'd like an option to have a "group" of custom fields, which can be reused.
Example would be: "Add a shirt to my order" button, which then reveals a "Select Shirt details: Color, Size, Quantity"
This button could be pressed up to X number of times to add X shirts to the order, each with their own Color, Size Quantity selections
Thank you.
