You can determine the content that appears in the header or footer of a desktop (typically above and below the body containing the books, pages, and portlets). For example, you can set up a campaign to display a piece of Web content in the desktop header when a user logs in.
Header and footer content is determined by the shell selected for the desktop.
To change the shell used for a desktop
You add content to a header or footer by creating or modifying a shell. See Creating Shells.
See Portal Samples for instructions on viewing a sample portal file.
