Vertical Navigation with drop-downs?

Is there a way to do drop-down style navigation when using the Vertical Navigation widget? I know this was possible with Sitefinity 3 but I don't see a way to accomplish it with version 5. I'm looking to do something like the attached screen shot which is running Sitefinity 3.7.

You could use the Clean Nav Control and then use something like the Suckerfish Technique for the flyouts
