# Menu and split button

**Test family:** `MNU`

- **MNU-001** Open from trigger, announce expanded state, place focus, and close on Escape/outside action.
- **MNU-002** Arrow/Home/End/typeahead navigation reaches enabled items in order and skips separators.
- **MNU-003** Disabled/hidden items match permission policy; direct routes remain protected.
- **MNU-004** Nested menus remain reachable without pointer precision and close in the correct order.
- **MNU-005** Split primary action and disclosure have distinct names, targets, and repeat behavior.
- **MNU-006** Menu placement survives viewport edges, zoom, scroll containers, and translated labels.

## Comprehensive per-item coverage

- **MNU-007** Verify absent, loading, initial, default, selected/open, disabled, read-only, invalid, pending, success, and error states are visually and programmatically distinct.
- **MNU-008** Activate with pointer, touch, keyboard, switch control, voice command, and automation APIs; produce one equivalent action per intentional activation.
- **MNU-009** Verify the accessible role, name, description, value/state, relationships, and focus behavior match the visible control.
- **MNU-010** Use adjacent labels or record names containing ASCII emoticons, emoji, kaomoji, RTL text, combining marks, and very long strings; render them safely without breaking activation.
- **MNU-011** Use labels with `&`, `<`, `>`, quotes, slashes, template delimiters, and CSV-formula prefixes; render text inertly in UI, logs, notifications, and exports.
- **MNU-012** Traverse with Tab, Shift+Tab, arrows, Home/End, Enter, Space, Escape, and platform conventions; never trap or unexpectedly move focus.
- **MNU-013** Double-click, double-tap, press Enter repeatedly, and retry after a slow response; prevent duplicate actions and expose truthful progress.
- **MNU-014** Change state while the control is focused, open, offscreen, or being announced; avoid stale accessible state and lost focus.
- **MNU-015** Attempt activation when hidden, disabled, read-only, unauthorized, expired, or stale through both UI and direct requests; enforce the server rule.
- **MNU-016** Interrupt the action with navigation, refresh, offline transition, timeout, server error, and session expiry; recover or roll back coherently.
- **MNU-017** Use two sessions to change the same state simultaneously; define conflict, ordering, and final-state behavior.
- **MNU-018** Reload, revisit, deep-link, back/forward, duplicate the tab, and restore a crashed session; preserve or reset state according to product intent.
- **MNU-019** Test the control inside forms, dialogs, menus, tables, repeated rows, nested landmarks, and virtualized content; keep names and targets unique.
- **MNU-020** Test narrow and wide screens, portrait/landscape, 200% text, 400% reflow, high contrast, reduced motion, and touch target sizing.
- **MNU-021** Translate and lengthen labels, use RTL layout, and change locale while state exists; preserve meaning, order, and action target.
- **MNU-022** Exercise 1, many, and very many repeated controls; keep rendering, interaction, and announcements responsive.
- **MNU-023** Verify analytics, audit events, notifications, and downstream requests occur once, contain the intended target, and omit unrelated sensitive data.
- **MNU-024** Change permissions or ownership between render and activation; reauthorize at commit time and explain rejection without leaking hidden data.
- **MNU-025** Undo, cancel, dismiss, reset, or restore where promised; make irreversible transitions explicit and require an appropriate confirmation/recovery path.
- **MNU-026** Test current and supported browsers/devices plus assistive technology combinations; do not rely on hover, color, animation, or pointer precision alone.
