Need to integrate navigation

[eluser]makkal[/eluser]
Hi everybody,

I am working in a web application development. In that i want to keep my navigation as a dynamic one. It should 3 level navigation menu by showing the active page.

Please give your suggestions on how to manage this. Is that i need to write any common functions in helper or plugins and calling it in the controller. Or some kind of function directly calling in view.

Kindly let me know your ideas. Thank you.
