[jQuery] How to go about writing a plugin that extends a core plugin like sortable

[Armand Datema]

Hi

I would like to turn my code for http://www.2dnn.com/DragnDrop.aspx into a
plugin. Right now its just standard coding and .sortable.

So lets say i would like my plugin to have the name of igoogle and extend
sortable

Is there a good example somewhere or can someone paste some code here so I
can go from there

thanks in advance

Armand
