How to achieve web site customization like iGoogle?

I'd like to know how to achieve web site customization like iGoogle (in particular I'd like to know how to drag/drop开发者_如何学C parts of web page (a.k.a. "prtlets") to different corners) ?

See this question how-to-use-draggable-sections-like-on-igoogle.
