Repeater Gadget
There may be a need to add related fields, multiple times for each document. While a table gadget can be used, it may not be the right format for certain use cases (text areas, rich text, recurring field sets with complex progressive disclosure).
That's when Admins can use the new "repeater" gadget. Admins can now drag a repeater field onto the form. Other fields can then be dragged into the repeater gadget and users can create multiple instances of this group of gadgets.
