I would like 2 drop down on the page.
The 2 dropdown change when we change the country.
Content in the drop downs are in a file like dropdown.txt
$france = array(first => 'val1', 'val2', 'val2');
$france = array(second => 'val5', 'val6', 'val7');
$england = array(first => 'val8', 'val9', 'val10');
$england = array(second => 'val11', 'val12', 'val13');
this information selected must appears on the final orders.
