_🎯 Functional Correctness_ | _🟡 Minor_ | _⚡ Quick win_ **Give the checkbox option list a role so that `aria-label` applies.** The `div` has no role. Assistive technology ignores `aria-label` on a generic element. Add `role="group"` so the "… options" name is announced. <details> <summary>Proposed fix</summary> ```diff - <div className="directory-facet-options" aria-label={`${label} options`}> + <div role="group" className="directory-facet-options" aria-label={`${label} options`}> ``` </details> <!-- coderabbit-global-learning v1 gid=130cb51964a65a32 scope=protocol --> <!-- suggestion_start --> <details> <summary>📝 Committable suggestion</summary> > ‼️ **IMPORTANT** > Carefully review the code before committing.
