jQuery select the same OPTION on three SELECT drop downs with one action

Answer 1

This is pretty much it. I'll work up an example.

$('#select1').change(function() {
   $('#select2').val($('#select1').val());
   $('#select3').val($('#select2').val());
});

Edit: The example: http://jsbin.com/ahema

And TStamper has a very good point, make sure you put in the ID, or it won't work. (you can see that in the example)

<select --> id="select2" <-- type="hidden">
  <option value="Sadan">Volvo</option>
  <option value="Sadan">Saab</option>
  <option value="Sport">Mercedes</option>
  <option value="Sport">Audi</option>
</select>
