Update dropdown item in database

I am dealing with a supplier registration, in the city and state fields there is a dropdown that consumes an API, I created a button to be able to update registrations, how do I make the dropdown field bring the existing value in the database? in simple fields I managed to do this with Initial Content, but in dropDown it doesn’t have that option and in placeHolder it even appears but not as data inserted in a cell, but as information about the field, which ends up disappearing with the data when I update .

Thank you very much!

Hi @ativuspcp
You can use default value for dropdown
For example:-
