Creating Hidden Website Pages
First, select "Websites" from the Navigational Menu. Click on the domain name of the website that you wish to add the hidden website page to. Click on the "Navigational Menu and Pages" widget from the website widget page.
Select "Add Page"
If you do not wish to have a link in the Navigation Menu area to a page you are creating, select "Do Not Include In Menu" in the "include in Menu" drop down box when you are editing the new page.
This feature is useful if you wish to create a "drill down" set of pages.
For example, if you wanted to create a page with a bulleted list of subdivisions then each subdivision name would be a link to a page about that subdivision.
You would select "Include In Menu" for the primary subdivision page, then select "Do Not Include In Menu" in the "include in Menu" drop down box all the 'sub' pages you create that provide information about each subdivision. This way only the primary page will appear in the navigation menu as a link.
