The page creation window lets you change the following settings:
The name of the new page.
The type of page — for example, category or content. This field is only shown if multiple types of page are available.
The page whose content should be copied to create this page. Choose Blank page to create a page containing only the shared areas (the header, navigation, and footer).
The visibility of the created page. Shown creates a page visible in navigation menus. Hidden creates a hidden page. Private creates a password-protected page accessible only by the site owner account; this option is only available to the site owner account.
Click Create to create the page. Click Cancel to return to the navigation editing window without creating a page.
