I have developed a ZenPack to demonstrate lots of different ways to add menus.  Largely it demonstrates techniques with Zenoss 3 though there are a few bits that also use Zenoss 2.x techniques.

You can find it on the standard ZenPacks page at docs/DOC-12937 and the code is on github at https://github.com/jcurry/ZenPacks.skills1st.MenuExamples .  Check at this github link for the extensive README.markdown documentation.

Please provide updates and feedback.

Cheers,

Jane
