On the right side of each subgroup above the list of questions is a navigation hierarchy. An example for the Cocoa Touch group is the following:
Apple Developer Forums/App Frameworks/Cocoa Touch
The items in the hierarchy used to be clickable. In the Cocoa Touch example, I could click the App Frameworks part and see all the recent questions in the App Frameworks section of the forum. Now clicking the items in the navigation hierarchy does nothing. I tested on both Safari and Firefox.
Is this new behavior in the navigation hierarchy expected behavior, or is there a bug in the forums?
