This field controls if Lektor should process the page into a build artifact. By default each page is built into a build artifact (HTML page) and each attachment is processed. This can be prevented by setting _hidden to yes.

This also automatically applies to all children of a page unless they forcefully override this setting.

This is useful for more advanced setups like Single Page Applications.

Hidden pages are automatically also removed from the .children property of records but stay available for querying via the pad.
