jQuery Sortable - events being called too many times

Question

I have a list with class x and in that list is a number of lists with class y.

It is possible to drag an item from any of the sublists to any of the other sublists

Answer 1

You should use the stop event for updating the ordered list.

For example:

        $("#List .Items").sortable({
            stop: function(e, ui) { 
                // update items
            }
        });
