Consider this page "WHO WE ARE", it shows photos of the management team. Notice the secondary level navigation on the left.
Now imagine, I click the photo of John and go down to a new page called "John" and I want the ability to drill down to other John-related pages.
My question is whether the secondary level navigation should always stay exactly the same no matter how far I go down? Or can I replace it each time with a new lower-level secondary navigation that is appropriate to the page, like below...
It feels great to be able to keep the secondary navigation on each page only specific to the page I am on, but feel that this is a misuse of what secondary level navigation actually is.
Note: This is just an example, I'm interested in the uses and misuses of secondary navigation. John and all his unnecessary pages which could just easily be tabs on a single page do not exist :)
