Nested Sortables

Nested Sortables is a class to provide sortable-like function on a nested element.

How to use

Include the script at the top of your page, and then set up an instance with a reference to a UL or other similar nested element:

new NestedSortables('nestedElement', {
    collapse: true,
    events: {
        onStart: function(el){
            console.log('started sorting');
        },
        onComplete: function(el){
            console.log('stopped sorting');
        }
    }
});

This code is effectively a MooTools 1.3 port of some 1.1 code written by CrazyDave. I can't provide a link to his website as it doesn't seem to exist any more. But on the off-chance he reads this - thanks for some great code!
