Potentially it can be simplified.

Thanks, Hopki, or answer! That enough with link to tutorial or sample! Here are the last edits of menu idea. There are of 3 button menus (look image below) . p.s. 2 (second) button menu should stay also on State 6; 7; 8. 3 (third) button menu should stay also on State 9; 10; 11. Skin.zip 2021-06-08 ...

Hello!
I am new in GG Object2VR.

Is possible in next State change Button row to another, and returning get them back. (look image below)
Or just make some sliding button with menu on Mouse hover?

Thanks!
