<select style="width: 80px;" class="text ui-widget-content ui-corner-all" id="metalist"> <option value="4d5e3a8c418416ea16000000">wikipedia</option>   <option value="4d5e3a8c418416ea16010000">twitter</option>   <option value="4d5e3a8c418416ea16020000">dbpedia</option>   <option value="4d64cd534184162629000000">test</option>           </select>
