Thanks for the reply.

following is the code which i am using to get the sub types from the database using jquery, ajax and php.

$('#TypeID').bind('change', function (Event) {
var typeid= $("#TypeID").val();
if(typeid=='' || typeid==null)
typeid=0;
$.ajax({
url: "/ajax/get_subtypes.php",
type: "POST",
data: "ticket_type_id="+typeid,
dataType: 'json',
cache: false,
success: function (data) {
$("#DynamicField_subtype").html(data['sub_types']);
}
});
});

But when I select any value from type drop down, It show the subtypes for a moment and then get blank.
