[jQuery] Create a Menu Draggable and Dropable to a target


I need your help;
I want to made a Drag and Drop Menu with jQuery, with target areas on
top, bottom and right side of my site.
I don't know how made a Draggable object fit to 100% the height and
Width of your target and only accept to be drop one target.
The iGoogle: http://www.google.com.br/ig -> have more or less the
effect that i want to applicate in my website. But in iGoogle, the
Draggable DIVS are positioned on various places on the screen.
How can i make this?
