HTML5 Sortable is a new cool (and better) jQuery plugin that allows you to easily create sortable lists and grids using the native HTML5 drag and drop API. Being lightweight and using new HTML5 API, the plugin supports both grid and lists style layouts having a similar behaviour to the jQuery-UI sortable plugin.
The plugin is free of use and comes with some neat options to make your implementation go easy. There are a couple of demos that you can find here and options are provided also. Currently, the sortable plugin works great in IE 5.5+, Firefox 3.5+, Chrome 3+, Safari 3+, and Opera 12+.
