When to use it

Use Checkbox for an on or off choice in a form or a list selection. Pair it with a label element.

Installation

How you get it

Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.

Use Liro's Checkbox for this.
Install it: npx shadcn@latest add @liro/checkbox
(the @liro registry is set up in components.json, with LIRO_KEY in .env.local)
Import it from @/components/ui/checkbox.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.

For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Free components install through the @liro registry with your CLI token: see the Namespaced tab.

Usage

components/terms.tsx
import { Checkbox } from "@/components/ui/checkbox";

export function Terms({ accepted, setAccepted }: { accepted: boolean; setAccepted: (v: boolean) => void }) {
  return (
    <label className="flex items-center gap-2 text-sm">
      <Checkbox checked={accepted} onCheckedChange={(v) => setAccepted(v === true)} />
      I agree to the terms
    </label>
  );
}

Accessibility

  • Keyboard reachable throughout, in visual order
  • Focus trapped in overlays, Escape closes them
  • Focus returns to whatever opened it
  • Live regions announce what changed, not that something did
  • Honours prefers-reduced-motion

Responsive behavior

  • Sizes to its container, not the viewport
  • Usable from 320px up
  • Pointer-based interaction, so trackpad and touch both work
  • No hover-only affordances
