Roll-up distinct selections in dropdown to parent row

Christine Mick

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?

I tested a formula out a bit and have pasted it below:

=IF(COUNTIF(CHILDREN(), "Red") > 0, "Red") + " " + IF(COUNTIF(CHILDREN(), "Yellow") > 0, "Yellow") + " " + IF(COUNTIF(CHILDREN(), "Green") > 0, "Green")

A few caveats on this:

1. Don't copy and paste the formula in your sheet. (Some times the quotes and parens get messed up and Smartsheet can't read them if they're copied from somewhere like the Community site.)

2. If you're using a symbol column, only one symbol can be displayed in the column at a time. With this formula, for example, you'll see the text string "Red Yellow" in the cell instead of a red symbol and a yellow symbol.

That could get crazy with large dropdown lists. Prefer a solution that does not require I hard code the selections in the formula as I could potentially have 20-30 options to select from.
