Search_field

Hi…

I am wanting make a helper for a search field. The laytou will follow. A
text_field(person_id for example), a button, that call a screen of
search, wich a list. When click a one row of list, the screen will
close, and code of person(for example) show in text_field(Thar one of
person_id).

Already exists one plugin that it makes this?

I found I find odd not to find something on this, therefore in
applications, that is a trivial action.
