Integrating sub- and side-level navigation

The basic idea around integrating sub- and side-level navigation into the app is to provide context-aware sub-views that change based on the active view. For example, when we are on a list page as opposed to editing an item, we may want to show different elements in the navigation. An e-commerce site is a great example of this. Imagine Amazon's search result page and product detail page. As the context changes from a list of products to a specific product, the navigation elements that are loaded also change.
