  <p><strong>Steps</strong></p>
  
  <ol>
  <li>Select a country from a dropdown list.</li>
  <li>The city dropdown list will fillup automatically with the list of cities of the selected country.</li>
  <li>If state is available for that country then state list will be visible with all state list of that country.</li>
  </ol>
  
  <p>Then I need to validate the selected city, state and country.</p>
  
  <p>Do you have any ideas?</p>
  
  <p>Thanks in advance</p>
