It would be very useful from a UI perspective to give Group fields a “Collapsible” true/false property. If set to true, it would show an arrow up/down button similar to Flexible Content and Repeater records. Clicking the button would collapse the group so that only the label is visible.
Does this do what you need?
For feature requests you should contact the developers.
As a work-around you could use a repeater with min and max rows set to 1.
Any fix for collapsing Group fields? Thanks
