Red Hat Documentation breadcrumbs have changed

​In order to provide consistency across the Customer Portal and avoid confusion in the many areas where the pattern is not supported, Documentation breadcrumbs have been modified. Breadcrumbs now function solely as one-dimensional, user-orienting navigation trails instead of attempting to replicate the existing navigation scheme for products and versions via dropdown menus. "Consistency breeds familiarity and predictability, which breed usability." [1] With this change, navigation is now consistent across the Customer Portal and all Red Hat Documentation, and we can focus on forthcoming improvements to the primary Documentation navigation.

Drop-downs such as this example are removed.

Filtering is handled on the product splash page
