# Install and place "autocomplete-001" (Datalist Field) from VibeUI

## 1. Install first — do not skip, do not recreate
Run this exact command before writing any code:
npx shadcn@latest add https://vibeui.ru/r/autocomplete-001.json

Registry item: https://vibeui.ru/r/autocomplete-001.json
Installs to: components/vibeui/autocomplete-001.tsx (the exact path follows this project's components.json aliases).
npm dependencies: none.
Registry dependencies: none.

Install it from the registry. Do not recreate it from the description,
do not substitute a similar component from another library, and do not
rewrite it to match the project's existing style.

## 2. What it is
Suggestions on a native datalist: the browser owns the list and the filtering, and there is no client code at all.

A field with suggestions on a native datalist: the browser renders and filters the list, the component holds no state and survives without JS. Zero dependencies, one file, its own light surface.

## 3. How to use it
import { Autocomplete001 } from "@/components/vibeui/autocomplete-001"

<Autocomplete001
  label="City"
  options={["London", "Berlin"]}
/>

Read the installed file for the full prop list.

## 4. Where to place it
This is a small inline component. Put it exactly where the user asked,
inside the existing markup. Do not create a new page, section or
wrapper for it. If a similar control already sits in that spot,
replace it instead of adding a second one.

Placement: ___
(The user fills this line in. If it is still blank, ask where to put it
instead of guessing.)

## 5. Keep exactly as installed
- the local --vibeui-autocomplete-001-* palette — do not swap it for your theme tokens
- the datalist instead of a hand-rolled list: it is announced by screen readers and survives JS being off
- the label/htmlFor and aria-describedby wiring — without it the field is nameless
- the built-in light surface: on a dark page the label would otherwise vanish
- autoComplete="off" on the field: browser history over a datalist shows two lists at once
- the 2.5rem field height — a thumb has to hit it on a phone

## 6. You may change
- the label and placeholder
- the options array — where suggestions come from
- the hint text under the field
- the accent through the accent prop — the focus ring

## 7. Rules
- The dropdown's look belongs to the browser: datalist rows cannot be styled. If you need your own, take autocomplete-002.
- A datalist does not restrict typing: it suggests, it does not constrain.
- Do not hand over huge lists — the browser renders every option at once.
- Do not lift the CSS variables into globals.css: the component has to stay a single file.

## 8. Verify
- it renders with no console errors;
- it looks like the preview on the VibeUI page you copied this from;
- if it does not, you changed something listed in section 5 — put it back.

For developers

npx shadcn@latest add https://vibeui.ru/r/autocomplete-001.json
https://vibeui.ru/r/autocomplete-001.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-autocomplete-001-*. Поле связано с <datalist> через list и общий useId, подпись — через htmlFor, подсказка под полем — через aria-describedby. Стрелка нарисована двумя бордюрами, поэтому иконочный пакет не нужен. Серверный компонент: хуков состояния нет.

Component source

The same file your agent installs. Here in case you would rather copy it by hand.

import { useId } from "react"
import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Autocomplete001Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children"
> & {
  label?: string
  hint?: string
  placeholder?: string
  options?: string[]
  accent?: string
}

// Идея компонента: подсказка на нативном datalist — единственный вариант
// автодополнения, который работает без единой строки клиентского кода и
// доживает до пользователя даже с выключенным JS. Список отдаёт браузер, он
// же фильтрует и озвучивает его скринридеру; наш код только рисует поле.
