ThemeSize

Tap List, Grid or Focus. Drag between them and cross back before releasing.

The interaction. The outline follows the gesture. Hysteresis gives each choice a clear threshold without flicker at the boundary.

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.

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/switcher-demo.tsx

'use client';

import { useState } from 'react';
import { MatrixSwitcher, type MatrixView } from '@/components/dot-matrix/switcher-entry';

export default function SwitcherExample() {
  const [view, setView] = useState<MatrixView>('list');
  return <div style={{ display: 'grid', justifyItems: 'center', gap: 24 }}>
    <MatrixSwitcher value={view} onChange={setView} />
    <p role="status" style={{ margin: 0, fontSize: 13 }}>{view[0].toUpperCase() + view.slice(1)} view selected</p>
  </div>;
}
