In some situations you may want to hide a page from the navigation — for example, a landing page for an e-mail newsletter. Note that a hidden page is still accessible to anyone who knows its address. For addition protection, a page can be password-protected.
To hide a page, click the Pages button on the toolbar, as shown in figure 1.
This will open the site map window, as shown below.
A Hide button appears next to each page that is currently shown. A Show button appears next to each page that is currently hidden, and the page name is shown in paler text. To hide or show a page, click the appropriate button. After hiding or showing pages click Close to return to the page.
