A fast, searchable multi-select that lets users filter a long list and toggle items with the keyboard or mouse. The dropdown updates in real time, shows selected rows with a checkmark, and uses a focused highlight for precise navigation—perfect for dense forms, filters, and admin tools.

• Keyboard navigation: ↑/↓ to move, Enter/Space to toggle, Esc to close

• Scrollable panel with sticky focus and smooth inertial scrolling

• Optional “Select all” / “Clear all” with indeterminate state

• Async/API and local datasource support with caching & error states

• Ranked results, fuzzy/partial matching, and result limit

• Grouped sections with headers, dividers, and optional sticky groups

• Disabled items, read-only mode, and initial values

• Chip/tag summary in the trigger or separate summary bar (optional)

• Form integration: validation, helper/error text, onChange/onValidate

• Virtualization for large datasets (thousands of rows)

• Accessibility: ARIA combobox, screen-reader labels, focus management

• Theming: radius, colors, shadows, spacing, typography

• RTL & localization-ready; responsive for mobile and web
