Hi Tim, you cannot rotate a shelf. So you will need to use display parts which can be rotated. If you need something resizable, and your good at the part editor you could use a back made from material the thickness of your cabinet depth, then do diagonal through cuts to make the bottle holes. HTH
I created one from a 12\" thick back in the PE. It re-sizes down ok, but when you go back to the original size things get ugly. Maybe someone else has some input.
