Adding an empty dropdown list to form and populate options using creator

Greetings

i need to work on a form where an employee would be selected from a dropdown list and then have data assigned to them through other fields in the form (like salary, work time, etc)..the idea i have in mind is to have an empty dropdown list with no options at all, and when the form is opened, a deluge function would run to fetch employee details from zoho people and populate the options of the dropdown list, is such a thing possible? i couldn't create a totally empty dropdown list from the GUI so could deluge help me with that?

Thanks
