Hello,

I would like to hide and show one or several <option> elements in a <select> element, under both IE 7 (or probably above), and Firefox 3.

My elements are :
<select name="source">
    <option value="A">A</option>   
    <option value="B">B</option>

  </select>

But I cannot hide option with such a call (neither in IE 7 nor in Firefox 3.5.7):

 $("select[name='source'] option[value='A']").hide();

Would you please tell me what goes wrong?
Thanks.
