Hello there,
This question would be better asked in the Starting with Gamestudio or maybe even AUG (Acknex user magizine) forums if you are new to GameStudio. You would get a much better response.
Or even try the search tool found above.

To answer your question though, Yes there are quite a few menu examples around. Unfortuantly because the lite-c part of 3DGS is still relativilty in beta stage I am afraid there not might be many examples in lite-c, However in saying that it's not that hard to
change the c-script language to lite-c I believe.

Good luck
