A required choice inside a form: the error shows up only after a submit, is tied to the field through aria-describedby and clears as soon as a row is picked.

# Install and place "combobox-010" (Required Choice) 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/combobox-010.json

Registry item: https://vibeui.ru/r/combobox-010.json
Installs to: components/vibeui/combobox-010.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
A required choice inside a form: the error shows up only after a submit, is tied to the field through aria-describedby and clears as soon as a row is picked.

A required combobox with form validation: the error message lives in role="alert", the field carries aria-invalid and focus returns after a failed submit. One file, zero dependencies.

## 3. How to use it
import { Combobox010 } from "@/components/vibeui/combobox-010"

<Combobox010
  label="Payment method"
  options={["Card online", "Cash on delivery"]}
  errorText="Pick a payment method from the list"
  onSubmitValue={(value) => console.log(value)}
/>

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-combobox-010-* palette — do not swap it for your theme tokens
- showing the error only after a submit: highlighting while typing reads as an accusation
- aria-invalid together with aria-describedby — without the pair the message is not read next to the field
- role="alert" on the message: it has to be spoken without stealing focus
- intercepting Enter in the field — otherwise the form submits instead of picking a row
- the block's own light surface: without it the dark text disappears on the dark catalog card

## 6. You may change
- the error copy through errorText and the hint through hintText
- the button caption through submitLabel and the list content through options
- the field caption through label and the placeholder through placeholder
- the accent color through accent and the error color through the danger variable

## 7. Rules
- noValidate turns off native hints for the whole form: other fields need your own checks.
- The error and the hint share one slot — texts of different length make the block jump, set a min-height if that hurts.
- The value does not reach a server by itself: the handler hands it over through onSubmitValue.
- 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/combobox-010.json
https://vibeui.ru/r/combobox-010.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра --vibeui-combobox-010-*. Корень — form с noValidate: браузерная валидация не умеет проверять рисованный список, поэтому проверку ведёт обработчик submit. Ошибка ставится только после попытки отправки, а не на каждое нажатие: ругаться на человека, пока он ещё заполняет форму, — худшее, что может сделать поле. Поле получает aria-invalid и aria-describedby, указывающий на сообщение или на подсказку, сообщение живёт в role="alert" и потому проговаривается без перевода фокуса. Enter в поле выбирает строку и не отправляет форму — иначе половина людей отправит её, промахнувшись мимо списка. После неудачной отправки фокус возвращается в поле.
