Fix exclusive navigation behavior

[farnabaz]

Assume

/foo
-- /bar -> exclusive
-- -- bar-content.md
-- -- /baz
-- -- -- baz-content.md

When user visits the /foo/bar/baz/baz-content we should show navigation list of /foo/bar because its exclusive and user visits one of its descendants
(Currently it should navigation list of /foo)

On the other hands we may need a back link on top on aside navigation to redirect user to parent navigation and make other sections of website navigable using aside navigations

Indeed, we need to define the levels of both Header and Aside navigations.

I think the Header should handle top level navigation (depending if it has children I believe), where the Aside is used for the current parent.

What do you have in mind to specify /bar as exclusive? Using a prop in the frontmatter of /bar/index.md?

There is a helper that can be used to retrieve top level navigation

Exactly, we have navigation.exclusive in the frontmatter data that do the trick
