Have a very simple array, how can I turn it into field choices for a drop down or multi select?

Hello I am hitting a database for an array of names and wanting to use them as choices for a drop down or multi select

Here is an example response:
["bill","bob","jon","brendan","jane"]

I have tried using map functions to no avail. Any ideas?
