Drupal Lite 7: Manage Navigation Menu
Your site's menu will appear at the top of every page, below the site header. When a page is added to the menu, you can choose to have it appear at the top level in the menu bar, or you can have the page appear in a sub-menu off of the main menu.
Note: Menu items will only appear if the page is published.
