Ensure ARIA roles contain required child roles

Screen readers like NVDA and VoiceOver navigate composite widgets (menus, tabs, trees) by moving between the required child roles. If a tablist contains <div> elements instead of role='tab', the user hears no tabs at all. JAWS announces 'list of 5 items' only when role='listitem' children exist inside role='list'. Without correct nesting, the entire widget becomes opaque to keyboard-only and screen reader users.

Quick Reference

• Container roles mandate specific owned child roles: tablist → tab, list/listbox → listitem/option, menu/menubar → menuitem, tree → treeitem, grid/rowgroup → row
• Missing required children break the accessibility tree so screen readers cannot enumerate items or announce counts
• Use role='none' or role='presentation' on purely structural wrapper elements inside the container to avoid invalid nesting
• Applies to WAI-ARIA 1.2 required owned elements for composite widget roles

Check

Identify all elements with ARIA container roles (tablist, list, listbox, menu, menubar, tree, treegrid, grid, rowgroup, radiogroup). For each, verify it contains the required owned child roles per the WAI-ARIA spec: tablist must own tab elements; list must own listitem; listbox must own option; menu/menubar must own menuitem, menuitemcheckbox, or menuitemradio; tree must own treeitem; grid must own row (which owns gridcell); radiogroup must own radio. Flag any container roles missing required children.

Fix

For each container role missing its required children: (1) Add the correct role to each child element — e.g., add role='tab' to each tab button inside role='tablist'. (2) If wrapper <div> elements exist between the container and the required children for layout purposes, add role='none' or role='presentation' to those wrappers. (3) Prefer native HTML equivalents where possible: <ul>/<li> instead of role='list'/role='listitem', <select>/<option> instead of role='listbox'/role='option'.

Explain

WAI-ARIA 1.2 defines 'required owned elements' for composite widget roles — these are the child roles a container must contain for the widget to be valid. Screen readers build their understanding of a widget from this structure. A tablist without tab children means a screen reader user in Forms Mode will find nothing to navigate between. A menu without menuitem children will not be announced as a menu at all in some ATs. This is distinct from aria-required-parent, which checks the inverse direction.

Code Review

Review the rendered markup and interactive states that affect Ensure ARIA roles contain required child roles. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.
