Multi-instantiated data fields are presented in the end user form with an "add" button and a "remove" button, allowing the end user to duplicate the same type of field multiple times, and enter data in each one.
When you configure a multi-instantiated data field, you can specify a minimum and maximum number of times a user can duplicate it. You can also multi-instantiate a group of widgets.
