### Which frameworks are available for Combobox field?

Combobox field is available for React, Vue, Svelte, Astro, HTML. The live preview uses React; the source observations below apply to index.tsx. Check the selected port before relying on the same interactions.

### What does Combobox field depend on?

### What accessibility details are visible in Combobox field?

The React source for Combobox field includes: native elements (button, input); attributes and handlers (aria-activedescendant, aria-autocomplete, aria-controls, aria-expanded, aria-haspopup, aria-hidden, aria-label, aria-selected, onKeyDown, tabIndex); explicit roles (combobox, listbox, option); key comparisons (ArrowDown, ArrowUp, Enter, Escape). These are source observations. Verify accessible names, focus order and keyboard behavior in the composed page.

### How does Combobox field handle reduced motion?

Combobox field reads the motion preference in its React source through useReducedMotion(). Preference-dependent expressions in index.tsx: reduceMotion ? false : \{ opacity: 0, y: -6, scale: 0.98 \}; reduceMotion ? undefined : \{ opacity: 0, y: -6, scale: 0.98 \}. Check the full implementation, shared styles and selected port with reduced motion enabled; these observations do not establish that every animation stops.
