How to create a Navigatable Tree View Menu in MVC3

Question

I have to create a Navigatable Tree View in an MVC 3 project. This treeview has to be generated from the database. There will be 3-5 levels for this tree and the final node of the tree view will be "Insert Your Comment". When the user clicks on the final node - "Insert Your Comment" (there can be more than one final node), the control should open a new comments page where the user can add his/her comment. Has anyone got any idea about doing this? I am using MVC3 (Razor). Thanks,
