Nestable, sortable and dragable categories

Nestable, sortable and dragable categories:

In the project I'm working on we wanted to have a Category model which we wanted to be nestable. But we also liked the user to have a draggable interface to manage and rearrange the order of his categories. So we chose awesome_nested_set for the model and jQuery.nestedSortable for the UI.

It took me some time to arrange things to work properly so I wanted to share my work in case it helps anybody.

Before beginning
