Hi Jason,

Thanks for looking into this. When I view source the div and select is correct:

<div class="piklist-field"><select 
  id="_post_meta_passenger_details_0_passenger_passenger_details_0" 
  name="_post_meta[passenger_details][0][passenger_passenger_details]"
  class="_post_meta_passenger_details_passenger_passenger_details piklist-field-element" data-piklist-field-group="a8a35be" data-piklist-field-sortable="1" data-piklist-field-addmore="1" data-piklist-field-addmore-actions="1" >
          <option value="" selected="selected">Select</option>
                <option value="Passenger 1" >Passenger 1</option>
                <option value="Passenger 2" >Passenger 2</option>
                <option value="Passenger 3" >Passenger 3</option>
                <option value="Passenger 4" >Passenger 4</option>
        </select></div>

But when viewing the page the select and div are wrong because the css for .piklist-field. is not applied to the select element.
