The Toolbar component has been designed, keeping in mind the WAI-ARIA specifications,
and applying the WAI-ARIA roles, states, and properties along with keyboard support for people who use assistive devices. WAI-ARIA
accessibility support is achieved through attributes like aria-orientation, aria-disabled, and aria-haspopup. It provides
information about elements in a document for assistive technology. The component implements keyboard navigation support by
following the WAI-ARIA practices, and has been tested in major screen readers.
The Toolbar element is assigned the role of toolbar.
