How to arbitrarily separate navigation items using simple-navigation?

I can't figure out how to configure my navigation so that I can call out different parts in different places in my layout, other than to use the 'level' system provided.

Really my navigation isn't two 'levels' - I just want some of it rendered in one div and some rendered in another.

I could hack my application's navigation such that one part is nested within another and use render_navigation :level => 2, but if there's a more sensible way to go I'd much prefer it!

Ideally I'd like to be doing something like: (haml)

#foo= render_navigation :part => "main"
#bar= ren开发者_如何学Pythonder_navigation :part => "extra"

Thanks.

Turns out you can specify different navigation sections in separate config files and call them with :context => "foobar"
