Outcome: Use Editable Combobox to solve this user need without losing the current context. User context: Type “Tai” to show Taipei and Tainan. Then use the arrow keys to choose. Recommended pattern: Editable Combobox. Why it fits: Use it for long searchable lists, autocomplete, or choices that allow a custom answer. Do not use it when: Never call a plain menu or a native select a combobox because they work differently. Product requirements: Define the default, loading, empty, error, success, and recovery states. Keep user input. Give clear feedback after every action. Accessibility and resilience: Use semantic HTML, full keyboard access, and visible focus. Make the layout work when zoomed and support reduced motion. Follow the project’s current rules. Do not add a new UI library unless the project already uses it. Acceptance criteria: The main task works with keyboard only and at 320px width. Focus and status changes are announced. Check loading, failure, retry, cancel, and reduced-motion paths. Evidence and limits (evidence boundary): The standard covers only the listed scope. It does not choose the visual style, product decision, or Vibulary example. Unknowns to confirm: Product wording, data source, analytics events, supported devices and languages, and platform limits.
