The standard navigation menu uses three levels for organisation. The highest level contains three group menus: 'E-Commerce', 'Content' and 'Settings'. Each group has several top level menus under it. Top-level menu items are fly out menus. This means when selected, the top level menu expands to display its menu items. These menu items are page links. For example, to access the 'Roles' page, the user needs to navigate to the 'E-Commerce' group, click 'Users ', then 'Roles'.
