2) if use the:

<option class="no-state" value="germany">germany</option>

and use jquery read it give me value germanyspain (which correct not want)

$('.no-state').val();

html part

<div id="country">  <select>      <option xyz="no-state" value="germany">germany</option>      <option xyz="state" value="usa">usa</option>      <option xyz="no-state" value="spain">spain</option>  </select> </div>  <div id="state" style="display:none" >  <select>      <option value="utah">utah</option>      <option value="new york">new york</option>      <option value="california">california</option>  </select> </div>

jquery part

$(document).ready(function(){     $('#country').change(function() {         if (the value of "xyz" tag === 'no-state')          {         $('div#state').hide();        }        else       {         $('div#state').show();       }     }); });
