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 Organise pages button on the toolbar, as shown in figure 1.
This will open the page organisation window. Click on the Site map tab, as shown in figure 2.
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.
