Answer 1

Something along these lines will work. It wraps your "Detail" selects in a container to make selection somewhat simpler.

$("#myddl").change(function()
{ 
     $('.detail').find('select').val($(this).val());
});​

Use $.on to bind to the "change" event. From here we target all select elements whose id begins with Select - which includes all of those below. Then we set their value(s) to that of the current one.

​$("#myddl").on("change", function(o){
   $("select[id^=Select]").val(o.target.value);
});​​​​​​​​​​
