title: Cascading drop-downs in MVC 3 Razor view
body: <p>I am interested in how to implement cascading dropdown lists for addresses in a Razor view.  My Site entity has a SuburbId property.  Suburb has a CityId, and City has ProvinceId.  I would like to display dropdowns for all of Suburb, City, and Province on the Site view, where e.g. the suburb dropdown will initially display "First select a City", and the City dropdown, "First select a province".  On selecting a province, cities in the province are populated etc.</p>
  
  <p>How can I achieve this?  Where do I start?</p>
