anticipated thanks!

edit

i've posted wrong question. looking easyest method of doing this. css / js / jquery.

simply got selected text , wrap in span length , , resize select

try example : 

     <select id="sel">          <option value="aaaa">aaaa</option>          <option value="aaaaaaaa">aaaaaaaa</option>          <option value="aaaaaaaaaaaa">aaaaaaaaaaaa</option>          <option value="aaaaaaaaaaaaaaaa">aaaaaaaaaaaaaaaa</option>          <option value="aaaaaaaaaaaaaaaaaaaa">aaaaaaaaaaaaaaaaaaaa</option>      </select>       <span id="hidnspan">       <span>  <script>  $(document).ready(function() {     $('#sel').change(function()     {         $('#sel').width( $('#hidnspan').html($('#sel').find(":selected").text()).width())     }); });   </script>
