Model Wheel

An endless drum in CSS 3D: rows bend away toward the edges and fade, and the one in the middle lands on a raised band in full ink. It spins a lap on first view, turns by drag, scroll, click or keys, and can cycle through names on its own as a hero piece.

The decision inside it

It always lands on a row, and says so

A throw is projected forward, rounded to the nearest row and carried there by a spring, so it never rests half a row off. Then it calls onLand(name, index), which makes it a real picker or slot reveal, not only decoration.

When to use it

Use Model Wheel for names on a turning drum that always lands on a row: a picker with onLand, a slot-style reveal, or a hero piece that cycles on its own. For a real model menu with prices use Model Picker.

Installation

How you get it

Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.

Use Layro's Model Wheel for this.
Install it: npx shadcn@latest add @layro/model-wheel
(the @layro registry is set up in components.json, with LAYRO_KEY in .env.local)
Import it from @/components/ui/model-wheel.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.

For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Pro components install through the @layro registry with your CLI token: see the Namespaced tab.

Usage

components/model-reveal.tsx
import { ModelWheel } from "@/components/ui/model-wheel";

export function ModelReveal({ choose }: { choose: (name: string) => void }) {
  return <ModelWheel items={["Swift", "Balanced", "Deep", "Vision", "Scribe"]} defaultValue="Balanced" onLand={(name) => choose(name)} />;
}

States

All of them are drawn by the component. None is left for you to design.

  • Spinning
  • Landed
  • Dragging
  • Cycling
  • Reduced motion

Accessibility

  • Keyboard reachable throughout, in visual order
  • Focus trapped in overlays, Escape closes them
  • Focus returns to whatever opened it
  • Live regions announce what changed, not that something did
  • Honours prefers-reduced-motion

Responsive behavior

  • Sizes to its container, not the viewport
  • Usable from 320px up
  • Pointer-based interaction, so trackpad and touch both work
  • No hover-only affordances
