• Async data source (API/DB) with loading & empty states

• Virtualized list for large datasets (smooth scrolling)

• Keyboard navigation & screen-reader labels (accessibility)

• Portal/overlay rendering with smart positioning & outside-click close

• Theming: colors, radius, elevation, chip style, spacing, typography

• RTL support and localization-ready placeholders/labels

• Form-friendly: onChange/onValidate, error text, reset & state persistence

Use cases
