1) About is the parent of Vision. How to write the if conditional ?

This : pagename == ‘vision’ does not work. The url should be:https://ocklaw.com/new/about/vision

2) Is it possible to write a new page without showing it on the top navigation ? I would like like that page to be linked by a custom side navigation.
