jQuery Sortable is a flexible, opinionated sorting plugin. It enables items in a list (or table etc.) to be sorted horizontally and vertically using the mouse. Supports nested lists and pure drag/drop containers.  Demo

jQuery Sortable does not depend on jQuery UI and works well with Twitter's Bootstrap (You can even sort the Bootstrap navigation).
