Viewing the slide like that does indeed not work. However, they’ll show up just fine on the top of your website 🙂 On the frontpage the slider is unfolded, on the other pages it’s folded by default. You can change this in the theme settings under “Appearance -> Theme settings -> Slider”.
I also noticed that you haven’t set up the navigation menu yet. Please check out our tutorial on this to get this looking great: http://www.redfactory.nl/themes/therestaurant/2010/10/17/create-a-navigation-menu/. Especially step two is important here.
Hope this helps you a bit 🙂 If not please let me know!
