Wordpress Re-usable Custom Widget

I created a custom widget for wordpress. But I can only use it once. I can开发者_如何学Go't assign multiple instances of the widget to my sidebars.

Can anyone show me sample code on how to make my custom widgets re-useable?

Using the 2.8 widget API, widgets are natively re-usable.
