# Select Styled native `` with pixel-true heights (24–48) and an error state. Inside a Field, id/aria-describedby/aria-invalid/required are wired automatically (D49). ## Props | Prop | Type | Default | Required | Description | |---|---|---|---|---| | `size` | `24 \| 32 \| 40 \| 48` | 32 | no | Height in px (24 \| 32 \| 40 \| 48). Replaces the native `size` attribute (which sets the visible option-row count on a listbox-style ``) with the design system's control height in pixels. | | `error` | `boolean` | false | no | Show error styling. Inside a Field, the Field's error also lights this. | | `ref` | `Ref` | — | no | Forwarded ref to the underlying `` element. | | `className` | `string` | — | no | Additional CSS class name(s) merged onto the component's root element. | ## Keyboard & assistive tech | Keys | Behavior | |---|---| | Tab | Focuses the native . | | Arrow keys / typeahead | Native option navigation. | error: same contract as Input — sets a red border only. Inside a Field, aria-invalid and aria-describedby are wired automatically (D49); standalone, pair them yourself. ## Theming Override `--psi-select-*` custom properties at any scope; interactive states derive automatically (L - 0.04 hover, L - 0.08 active). ## Rules - One accent per visual group; everything else neutral or ghost. - danger only for actions with real consequences. - Sizes are px numbers (24|32|40|48), never S/M/L. - Typography tokens are --psi-text-{size}-{lineHeight}-{weight}. - Override component tokens (--psi-{component}-*), not semantic tokens, for one-off theming. - --psi-button-font overrides button typography across all sizes (documented D34 override; ember → mono). - Wrap labeled form controls in Field — label association, description/error line, aria-describedby and aria-invalid come wired; don't hand-roll label+message rows. - Use Dialog for blocking modal flows — title/footer slots, dismissible gate; danger stays on the footer Buttons, one accent per group.
