We need the ability to show the secondary navigation on the home page only. We do not need the secondary navigation on any of the other pages.

The reason we need this feature is because we have our documentation categories as multi-level items. And on the home page, it makes sense to have the categories under which users can find the sub-categories. However, when you open an article, it does not make sense to have the same secondary navigation when you can just browse all categories anyway on the left-hand side.
