Accessibility#

Screen Reader

MegaMenu component uses the menubar role along with aria-orientation and the value to describe the component can either be provided with aria-labelledby or aria-label props. Each list item has a presentation role whereas anchor elements have a menuitem role with aria-label referring to the label of the item and aria-disabled defined if the item is disabled. A submenu within a MegaMenu uses the menu role with an aria-labelledby defined as the id of the submenu root menuitem label. In addition, root menuitems that open a submenu have aria-haspopup, aria-expanded and aria-controls to define the relation between the item and the submenu.
