Tap to open, choose an action, or press Escape to close.

The interaction. Rows become interactive only when their whole target fits. Keyboard focus follows the opening and returns on dismissal.

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/menu-demo.tsx

'use client';

import { useState } from 'react';
import { MatrixMenu } from '@/components/dot-matrix/menu-entry';

export default function MenuExample() {
  const [selection, setSelection] = useState('Choose an action');
  return <div style={{ width: '100%', display: 'grid', justifyItems: 'center', gap: 24 }}>
    <MatrixMenu onSelect={item => setSelection(item.acknowledgement)} />
    <p role="status" style={{ margin: 0, fontSize: 13 }}>{selection}</p>
  </div>;
}
