Append Blank Option to Dropdown Items

Posted on by Community Power Pla... Microsoft Employee

Hello,

Scenario:

- 2 Sharepoint lists: "MAINLIST" and "PICKLISTS"

- They have columns in common ("Description" and "Test")

- Gallery Items set to "MAINLIST"

- Dropdown control within Gallery

- Dropdown Items set to:

Filter(
 PICKLISTS,
 And(
 Description = ThisItem.desc,
 Test <> ThisItem.test
 )
)

- Works like a champ!

Need:

- To add a blank option to the Dropdown Items

Do NOT need:

- The Default property to be blank (I already know how to do that with "AllowEmptySelection")

- I need the blank option so user can revert their selection

Any ideas?

Thank you

Hi @ericonline ,
This may not be what you are after, however I do this on all drop-downs involving reference list data (crew names / vehicles / job packs etc).
ClearCollect ( colWhatever, {TargetField: ""} ); Collect( colWhatever, ShowColumns( TargetList, "TargetField", "AnyOtherField/s" ) )
My Items is then
Sort( colWhatever.TargetField, Ascending )
Bear in mind also I am writing back to Text fields in the target, so my Update is generally a simple
DropdownName.Selected.TargetField
