# Phone Input (Notchset): prompt.md (v1.0.0)

- id: `phone-input` · version 1.0.0 · component · pro (Pro)
- category: Inputs
- build: Base UI (one set of files; its dependencies follow the build)
- install (this build): `npx shadcn@latest add @beautiful-ui-pro/phone-input`
- npm dependencies: none
- registry dependencies: utils, https://beautiful-ui.dev/r/notchset-foundation.json
- docs: https://beautiful-ui.dev/components/phone-input
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

A phone number field: a country key, the national number grouped as you type, a validity node, and a searchable list of 22 countries; it reports E.164 once complete.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: none beyond React.
- Files: `components/ui/notchset/phone-input.tsx`; shared code: `lib/beautiful-ui/notchset/instrument.tsx`, `lib/beautiful-ui/notchset/root.ts`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`.
- Builds: one set of files for both, but its dependencies come in Base UI and Radix builds. Install the one that matches the project (see Install): a free item's bare URL installs the Base UI build of it and its dependencies.
- Exports to keep: `PhoneInput`, `PHONE_COUNTRIES`, and every exported type.
- CSS: the install adds the notchset foundation (tokens, keyframes, motion levels) to your global stylesheet once. Nothing to import by hand.
- Re-running `add` (or `--overwrite`) re-applies those rules: put overrides in your own CSS, never in the installed rules.
- Tokens: retheme with the `--notchset-*` custom properties (`--notchset-check`, `--notchset-control-edge`, `--notchset-draw-from`, `--notchset-ease-bloom`, `--notchset-ease-travel`, `--notchset-fade`, `--notchset-focus-color`, `--notchset-focus-inset`, `--notchset-life-from`, `--notchset-life-ms`, `--notchset-node-blink`, `--notchset-node-bloom`, `--notchset-node-delay`, `--notchset-plate-color`, `--notchset-rise-from`, `--notchset-rule`, `--notchset-scroll`, `--notchset-signal`, `--notchset-sweep-to`). Never add Tailwind colour classes inside the component.

```tsx
import { PhoneInput } from "@/components/ui/notchset/phone-input";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `PhoneInput` | `phone-input` | The field. |
| `list` | `phone-input-root` | Field, help and list. |

Style a part with `[data-slot="<slot>"]` selectors or its `className`; keep the attributes when editing.

## Sound
- Keep every `data-slot` and `data-sound` attribute: the sound layer reads them.
- Installing this item adds no audio. Nothing plays until the app mounts `SoundProvider` once (install: `npx shadcn@latest add https://beautiful-ui.dev/r/notchset-sound.json`, import from `@/components/ui/notchset/sound-provider`); `useSound()` gives `muted` and `setMuted` for a mute control. Without a provider the audio engine never loads.

## Match the original
- Read `components/ui/notchset/phone-input.tsx` as the reference implementation before changing or recreating anything, and match it: sizes, colours per theme, motion timings, copy and behaviour.
- If you deviate (a prop you can't honour, a style you changed, a dependency you swapped), say so in your reply, part by part.
- Keep the accessibility contract, the keyboard map and the motion levels listed below.

## Use it when
- phone input, phone number, country code, tel, E.164, Notchset
- Collecting a mobile number for pages, 2FA or contact

### Not when
- International address forms with many fields: use a dedicated library

## Mistakes
- Store the E.164 value, not the formatted text

## Usage

```tsx
"use client";

import * as React from "react";
import { PhoneInput } from "@/components/ui/notchset/phone-input";

export function OnCallPhone() {
  const [phone, setPhone] = React.useState("");
  return (
    <form action="/api/on-call" method="post">
      <PhoneInput defaultCountry="PT" onValueChange={setPhone} />
      <input type="hidden" name="phone" value={phone} />
    </form>
  );
}
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `defaultCountry / defaultValue` | `string / E.164` |  | Where to start. |
| `onValueChange` | `(e164, country) => void` |  | E.164 once complete, "" until then. |
| `countries` | `{ iso, name, dial, groups }[]` |  | Your list (22 by default). |
| `error` | `string` |  | A server's rejection, in place of the help line. |

## Customising
- Colours: the component reads your shadcn tokens (`--background`, `--foreground`, `--border` …), refined by the `--notchset-*` tokens. The signal colour is `--notchset-signal` (it falls back to `--destructive`). Set tokens on `:root`, or on any container to retheme one area.
- Dark mode follows the `.dark` class on an ancestor (the shadcn and next-themes convention).
- Update later by re-running the install with `--overwrite` (review the diff if you edited it). Changelog: https://beautiful-ui.dev/r/changelog.json

## Keyboard

| Keys | Action |
|---|---|
| + | Open the country list |
| ↑ / ↓ | Move |
| Enter | Pick |
| Esc | Close |

## Performance

- Formatting and filtering are synchronous string work; the list mounts with the field.

## Responsive

- Fills its container; the list is 260px. 44px field on touch screens.

## Motion inventory

| Interaction | What moves |
|---|---|
| Valid | The node's centre pops in (300ms) |
| List | Unrolls (360ms); the highlight glides between rows (140ms) |

## Accessibility contract (preserve when editing)
- type=tel with autocomplete tel-national; the help line describes it
- The country key is a listbox button; the list's search field leads it with aria-activedescendant
- Short numbers are flagged on blur, not while typing

## Install

```bash
npx shadcn@latest add @beautiful-ui-pro/phone-input
```

Pro item: needs the `@beautiful-ui-pro` registry in `components.json` and `BEAUTIFUL_UI_TOKEN` in `.env.local` (https://beautiful-ui.dev/account). Setup: https://beautiful-ui.dev/docs/pro. Your components.json `style` picks the build: radix-*, new-york and default get Radix, base-* gets Base UI.

## Credits
- Built on shadcn/ui (https://ui.shadcn.com)

The notchset foundation (the tokens listed above, keyframes and motion levels) installs once with the first component; its CSS is public at https://beautiful-ui.dev/r/notchset-foundation.json.
