Is there a way to roll-up child dropdown selections to the parent row so that the selections show only once in the parent?
Example:
Dropdown contains: Red, Blue, Yellow
Child 1 selects Red
Child 2 selects Yellow
Child 3 selects Red
I found where I can use JOIN(Children()), but this will display Red, Yellow, Red in the parent.
I want to see only Red, Yellow
Is this possible?
