Back to (Not so) Simple ARIA Tree Views and Screen Readers
List items with nested links. The nested links have role="treeitem". Focus moves through the links.
Note that child node groupings are not nested directly within the link with role="treeitem", but are siblings to the link. This doesn't seem to hamper JAWS, NVDA, or ORCA, which assign appropriate relationships between treeitems and their sub-node groupings. It may have some effect in VO, but VO doesn't work with this treeview structure in any case.
