Use when applies to custom tree widgets built with role='tree', role='treeitem', and role='group'. Common in file explorers, nested navigation menus, org charts, and any UI where items can be expanded or collapsed to reveal children.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Provide accessible names for tree items
Tree widgets represent hierarchical data (file explorers, nested navigation, organization charts). Screen readers announce each focused treeitem's name, level, and position — e.g., 'src, collapsed, level 1, 1 of 3'. If the name is empty or generic ('folder', 'item'), blind users cannot distinguish between nodes and cannot navigate the hierarchy with confidence. VoiceOver on macOS uses the name to populate the rotor, and NVDA reads it as the user moves through the tree with arrow keys.
## Quick Reference
- Every element with `role='treeitem'` must have a non-empty accessible name
- Text content of the element is used as the name by default — ensure it is descriptive
- Use `aria-label` to override or supplement the visible text (e.g., adding file type context)
- Use `aria-labelledby` to compose a name from multiple visible elements within the item
- A treeitem with `aria-expanded` must also convey its expanded/collapsed state — this is separate from its name

How to install
mdr add thedaviddias/front-end-checklist/aria-treeitem-name@sha256:d9437450d7733b5dThe line at the top of this page pins the label git:20260529.7c05904, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
