Dropdown field: Option for unselect

Question
1

Is there a way to have a dropdown field populated with a data variable where the default option is “no option selected”?

I have configured the following dropdown field:

with this option list:

My problem now is, that the default option in the dropdown is always the first item in the option list. But I want it to be empty as a default. It is also not possible to switch it to “unselected” manually, it always jumps to the first option in the list (iOS preview app)

Yes, use CONCAT() or WITH_ITEM():
Something like:

CONCAT([{“label”: “no selection”, “value”: “null”}], your entire MAP formula here]

This worked perfectly. Thank you very much for your help!
