Extending VS 2010: to include additional items on Right Click context menu (add) on solution explorer?

I wish to create an additional item on the context sensitive right click "ADD" on the solution explorer in vs 2010.

Basically it currently looks like this

New Item
Existing Item
New Folder
Add ASP.NET FOLDER // ACTUALLY THIS IS A MENU with a SUB MENU
Class

What i am trying to do is create a new item similar to "Add asp.net folder" hence it will have subitems

Basically it will be something like this

Add JS items
     Add new model
     Add new plugin

Basically clicking on "add new model" or "add new plugin" will create a new file UTF-8 and include in the project. It开发者_C百科 will contain some default code.

I am having a real issue trying to find a good example of how to do this.

Any ideas where i should look?

Anybody seen anything similar?

THanks in advance

Here are some docs to point you in the right direction.

Basically commands and menus work the same throughout all of VS, one tricky part is just finding the right Guid of the parent menu that you want to hook in to.
