Thank you for giving me the two options! It does need some menu customizations, definitely, but nothing too extreme. It's a more dynamic version of the straight "sticky" menu and more work to implement. But the effect really is cool and I have a feeling it's catching on, based on how often I see it in new WP sites. Again I hope Joomlart begins offering some templates built this way, while also offering the more clean and simple "sticky" menu. It's not difficult to code, but many customers prefer to spend as little time coding as possible.
