title: django editable dropdown list populated from queryset
body: <p>I was looking for a possible way to make a django combobox populated from a queryset but I didn't manage to find sth relevant in the web. Is it possible to manage sth like the following?
  I have a modelform and I want to render a field as combobox. 
  Important: Not as the classic dropdown list using ModelChoiceField but as an editable dropdown list populated by queryset?
  I know I can use jquery for that but then how can I populate it with a queryset? </p>
