  • lotusNavMenuLarge - the class that also goes on the lotusLayout table for the apps mega menu.

Basic Implementation

TBD

Accessibility

The element that triggers the mega menu (a link or button) is assigned the attribute aria-haspopup="true." If the trigger element is a link, it should also have a role="button" attribute.

If the mega menu is not a DOM child of the triggering element, the triggering element should have an aria-owns property whose value is the id of the mega menu.

Add an aria-label for the menu (like "mail menu") on the lotusNavMenu div. Add display:none to initially hide this div.

The menus are created using a table and marked up using an ARIA Grid. Put role="grid" on the table element. Put role="row" on each tr tag. Put role="rowheader" on each th tag in a row. Put role="columnheader" on any th tags in the top row only. Put role="gridcell" on any td tags.

Some of the mega menus are considered complex tables because they have a colspan on one or more of the cells. For those tables, you need to scope the th tags (scope="col" or scope="row").
