Drag a handle, or use Space, arrow keys and Enter to pick up, move and place.

The interaction. Stable item identities preserve the moving row. The host owns the final order; Escape returns to the starting arrangement.

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/reorder-demo.tsx
'use client';

import { useState } from 'react';
import { MatrixReorder, type ReorderItem } from '@/components/dot-matrix/reorder-entry';

export default function ReorderExample() {
  const [items, setItems] = useState<ReorderItem[]>([
    { id: 'notes', title: 'Field notes', detail: 'Ideas worth keeping' },
    { id: 'voice', title: 'Coastal recording', detail: 'Audio · 02:24' },
    { id: 'motion', title: 'Motion references', detail: 'Collection · 12 items' },
  ]);
  return <MatrixReorder items={items} onChange={setItems} label="Your collection" />;
}
