shadcn's Select in Notchset: a 40px trigger whose value rolls, a panel under a leader with 48px options on a rail, one dot that travels to your pick before the panel closes, and disabled options that say why.
pnpm dlx shadcn@latest add https://beautiful-ui.dev/r/select.jsonpnpm dlx shadcn@latest add https://beautiful-ui.dev/r/radix-nova/select.jsonFree, no account or key. Use the command for your project's primitives: a radix-*, new-york or default style in components.json is Radix, a base-* style is Base UI. With the @beautiful-ui registry added, @beautiful-ui/<name> picks for you.
pnpm add @base-ui/react@^1The CLI adds the styles to the CSS file named in components.json (tailwind.css). Check that it points at your global stylesheet, that the project uses Tailwind CSS v4, and that the file is imported in your root layout. Installed by hand: paste styles.css into that file.
Import it and pass your content. The props that matter most are listed next.
