Now my gallery form is almost perfect but I can't change the combobox (with single select and search) to a dropdown because it contains a list of thousands of employee names (from the Office365-connector). Is there any chance this property could be made available for comboboxes?
The combobox has, since it was introduced, supported empty selection, so there's no need to set any property for that.
In the DefaultSelectedItems property from the combobox I had to enrich the formula with: If(EditForm1.Mode=FormMode.Edit;....;Blank()). I would not have guessed that myself. You're always welcome to screen the topic and give advise for best practices 🙂
