Save changes to follow the perimeter lights through progress and completion.

Demonstration request. No data is sent.

The interaction. One press starts one operation. Success completes the ring; rejection makes retry available without shifting the label slot.

One shared language. Permanent dots, selective light handoffs and clean outlined shells. Chalk, Carbon and Ember carry the family across sizes and themes.

Make it yours. The preview and installation use the same source. Pointer, touch and keyboard interactions share the same state model, with system reduced motion respected throughout.

Install

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

Usage

This is the working preview example. Save it in a separate file after installing the component. Recording, media clocks and requests are illustrative: connect their controlled state and callbacks to your application.

components/examples/action-demo.tsx

'use client';

import { MatrixAction } from '@/components/dot-matrix/action-entry';

export default function ActionExample() {
  return <MatrixAction onPress={() => new Promise<void>(resolve => setTimeout(resolve, 1200))} />;
}
