title: How to use PrimeNG Dropdown in Angular2 Model-driven form?
body: <p>Need help with <a href="http://www.primefaces.org/primeng/#/dropdown" rel="nofollow">PrimeNG dropdown</a> in an Angular2 <strong>model-driven</strong> form.  The PrimeNG documentation I have found only use template-driven forms.</p>
  
  <p>A sample code for the following would help greatly:</p>
  
  <ol>
  <li>an Angular model-driven form</li>
  <li>the form contains one PrimeNG dropdown and a submit button.</li>
  <li>the dropdown contains 4 cities (Moscow, Istanbul, Berlin, Paris).</li>
  <li>the user is required to change the selected city (to enable the Submit button).</li>
  <li>the dropdown can be programatically "initialized" to show one of the cities in the options list (e.g. Berlin) when the form first opens.</li>
  </ol>
  
  <p>Thanks.</p>
