Yes, you can create whatever menus you want. The welcome app provides menus
that are described in a models file but you can describe a a different menu
or describe a menu in a controller or module. Just follow the patterns you
see in the welcome code:
response.my_menu=[(T('Resources'), False, None,
[
(T('Documentation'), False, 'http://www.web2py.com/book',
[
(T('Preface'), False,
'http://www.web2py.com/book/default/chapter/00'),
(T('Introduction'), False,
'http://www.web2py.com/book/default/chapter/01'),
]),
]
)]
And then in your view:
{{=MENU(response.my_menu, _class='sf-menu')}}
