Hey timmse give me some hints on how can i do this

the question is, how to create custom fields for the form? Like this one.
I’ve tried to fake the selector of prefixes with a custom callback that fills the dropdown but now it’s impossible to make it looks well

two sticky fields, one is a selector and the other is a tel field.
