I want to draft a page within my site that doesn't need navigation (the rest of the site has and needs nav) its a page that is only seen by a membership who will have accessed the page through a password.
Ok, so it is very easy in this builder. Create the page under Pages on the left. Then, click on the Pages tab again, and click the two icons to the right of the page name. This will hide them in the desktop and mobile menu.
