Containment Toggle | Sean Lynch

Made of something. A corroded steel thumb, olive capsule and damaged seals around a gas-filled chamber.

The moment. The piston pushes vapour ahead of its travel. Switching back exposes persistent rust beneath the gas; native form reset restores the initial state.

Yours to adapt. Copy the component source, styles and materials. Functional text stays live, effects respect reduced motion, and the artwork requires no remote hosting.

Try it

Switch on, then off. The chamber remembers the corrosion.

Install

Add it with the shadcn CLI, or copy the source manually.

Release candidate: public installation becomes available after deployment. Use an existing React 19 project with shadcn initialized and a components.json file. The CLI installs the source, CSS, embedded materials, MIT licence and font notices together.

Terminal

npx shadcn@latest add https://seanportfol.io/r/grimkit-containment-toggle.json

Prefer a namespace? Register the registry once.

Terminal

npx shadcn@latest registry add @seanlynch=https://seanportfol.io/r/{name}.json

Terminal

npx shadcn@latest add @seanlynch/grimkit-containment-toggle

Usage

Copy this example into a separate file, not over the installed component. The @/ alias points to your source root. In Next.js this is a Client Component; Vite also accepts the directive. Replace demonstration actions with your application logic.

components/examples/containment-toggle-demo.tsx

"use client";

import { ContainmentToggle } from "@/components/grimkit/containment-toggle";

export default function Example() {
  return <ContainmentToggle label="Containment" name="containment" defaultChecked={false} />;
}
