Global navigation, also known as MegaNav, is a panel showing groups of navigation options all at once via a column structure. It includes a nested drop-down menu divided into groups by categories showing relationships between items. It also includes the Spotlight Banner component.
MegaNav is a standard global pattern that is used for large sites with large amounts of content and includes: panel/container, links, menus/lists/levels of navigation, business unit name/logo, and spotlight. By default, there are 3 levels of navigation: L1, L2, L3. The MegaNav, in most cases, isn’t modified by designers. However, there are some areas of flexibility, including:
The Spotlight is positioned on the right-most column by default, for ads/promotions. It can be positioned on the left-most column for copy that introduces, or briefly describes a section. You can also hide/turn off the Spotlight component.
Ensure all content text and background colors meet accessibility requirements on Color guidelines. Visually and programmatically relay states (expand/collapse) to the user. Relay keyboard interaction instructions to the screen reader user. Ensure all controls are keyboard focusable and recognized by assistive technologies and add a role when necessary. Use descriptive labels. Follow best practices on links and Schwab Accessibility guidelines.
