Sharepoint list item - custom drop down menu

To be able to customise Sharepoint Context menus easily using Javascript in a a Content Editor Web Part is extreemly powerfull and remarkably simple to get working. - see this article for guidance Customizing SharePoint Context Menus.

(Suplimental: The obove article is ok as far as it goes however to try to get the client side menu to carry out actions is not simple. You need to be skilled in Javascript and have a knowledge of the internal variable names Sharepoint 2007 users. [at least Sharepoint 2010 will have a client side dll!).
