page not in menu
Evgeny Zaritovskiy commented
In current WA version you will have to use this workaround: a) create invisible page b) add the page you need to hide from menu as a subpage to the invisible one. After that, you can reference the subpage by direct link, it will not be shown in menu.
In the next release 5.0 we are adding direct ability to control if a page should be shown or hidden in menu.
