hi @Danny_Dicaprio ,
You can create a collection in the OnVisible property of the screen or in the OnStart property of the app. For example, in the OnVisible property of the screen:

ClearCollect( CombinedControls, AddColumns( Controls, "DisplayValue", ControlID & " - " & ControlDescription ) )

This formula creates a new collection called CombinedControls, which adds a new column called DisplayValue to the Controls table, combining ControlID and Control Description with a hyphen.
Set the Items property of the dropdown to the new collection:

CombinedControls

To achieve this you would need to create a collection to create this column. However you can also create it with a Calculated Column in Dataverse and just use this column instead.
This way you could use every column of the tabele with DropDown.Selected.ColumnName

the other way you would need to find a way to LookUp to Dataverse for everithyng.

Let me know which way you want to use.
