Panoroma Application for Silverlight(WEB)

Question

Ok.Im building a product for a client using Silverlight 4 with Sharepoint 2010.But this question is about Silverlight.

You must have seen Metro-UI.This is the theme in Windows Phone 7 and ZUNE Software.I was looking for all over the net for a nice looking theme that can be applied in Silverlight Web projects,too.So i found what i was looking for in Tim Heuer's Blog: Cosmopolitan Theme .I've tried it.Its a perfect theme! But not that perfect for me.Because i have over 18 menus and after i used this theme it doesnt display after 10 menu items because screen resolution thing.

Now here's my question coming for you:
This theme is built for a couple of menuitems and there is no dragging feature there.I was wondering if the same Panoroma Application style can be applied for Silverlight Web Projects,too? I've looked everywhere on the net but no luck.

Is it possible to build a draggable menu just like in Panoroma Application?
