Write example jQuery code for autocomplete

I'm looking for example C#/.NET code that uses jQuery autocomplete to display a hierarchy (parent/child). The autocomplete should be tied to an initial hardcoded list of "parents". Selecting a parent from the first dropdown should automatically trigger a secondary autocomplete with a set of "child" options. Please use country/city as the relation ship. For example: I start typing "I" and autocomplete shows {Italy, Ireland, India} I then select "Italy" and a secondary autocomplete drops and shows me Italian cities {Rome, Naples, Florence, Venice} Both selections should be saved somewhere in the HTML/DOM as IDs Deliverable is a Visual Studio MVC solution/project with a simple page containing the autocomplete and all functionality described.
