Whats the difference between the “Published” and “Show in Menu” checkboxes?
When the Published checkbox is checked, your document is live and accessible on your site. If the document is not published, you can still see it when logged into the manager, but it will not be available to regular visitors to the site. The Show in Menu checkbox just sets a flag that the Wayfinder snippet (and other snippets) can use to decide whether or not to show the document in menus.
