"Not Working yet!" Is not helpful!!
If you would like help with something or like to help imporve the plugin then you have to be a little less vague.
In your screenshot I can see that the UI is really messed up, was it like that before you activated the contextmenu plugin? What browser+version are you using? Are there any JS errors? What exactly is not working?
I can see from the screenshot that the menu loads and all the options look to be activated/deacticated as expected, the spacing of the links is a little funny are you using a custom skin?
