Widget property
Description
Indicates whether the element’s orientation is horizontal, vertical, or unknown/ambiguous.
Note: In ARIA 1.1, the default value for aria-orientation changed from horizontal to undefined. Implicit defaults are defined on some roles (e.g., slider defaults to horizontal; scrollbar defaults to vertical) but remain undefined on roles where an expected default orientation is ambiguous (e.g., radiogroup).
