A: To hide a page, check the "Hide?" box in Page Properties.
By default, all pages are displayed in the navigation. For pages such as a Contact Sheet which need to be hidden, you'll need to hide the page using an option in Page Properties. This can be found by right-clicking on a page in the Websites pane, or by clicking the Page tab of your sidekick.
Click the arrow next to "Display in Navigation," and check the box next to "Hide?" to remove it from the Recursive Nav.
