Drag Auto Scroll

Extended Drag n Drop Library in Javascript.
I couldn't find a javascript drag and drop library which is capable of auto scrolling. So I made my own. I will update things when I get time. I am bad at explaining things. Please forgive me.
View a Demo and try to drag elements. See the inner scrolling of elements. Click on the draggable item with handle , press Enter key and use arrow keys to move item.

Features
