To get the order of the selected items as selected, you can do like
var form = $("form#my_form");
$(form).on('submit', function(){
$("ul.selected li").each(function(){
var selected_value = $(this).attr('data-selected-value');
if(selected_value){
$(form).append("<input type='hidden' value='" + selected_value + "' name='selected_items_values_in_order[]' />");
}
});
});
