Combobox
Form Field
A combobox inside a form: people see the caption while a hidden input with a real name carries the code, so the form submits normally and lands in FormData.

# Install and place "combobox-012" (Form 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/combobox-012.json
Registry item: https://vibeui.ru/r/combobox-012.json
Installs to: components/vibeui/combobox-012.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 combobox inside a form: people see the caption while a hidden input with a real name carries the code, so the form submits normally and lands in FormData.
A submit-ready combobox: a hidden input with a name carries the value code, the button is disabled without a choice, and the FormData payload is shown under the form. One file, zero dependencies.
## 3. How to use it
import { Combobox012 } from "@/components/vibeui/combobox-012"
<Combobox012
label="Delivery method"
name="delivery"
options={[{ value: "pickup", label: "Pickup from warehouse" }]}
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-012-* palette — do not swap it for your theme tokens
- the hidden input with a real name — without it the list is just a picture and FormData stays empty
- the split between value and label: the server must receive the code, not the visible caption that gets translated tomorrow
- disabling the button without a choice: submitting a required field empty is the most common complaint about such forms
- aria-activedescendant on the filter field, otherwise the row under the cursor is never announced
- the block's own light surface: without it the dark text disappears on the dark catalog card
## 6. You may change
- the field key through name and the list content through options
- the button caption through submitLabel and the field caption through label
- the placeholder text through placeholder
- the accent color through accent and the form width through max-width
## 7. Rules
- A hidden field takes no part in native validation: check the requirement in your own code or on the server.
- The FormData line under the form is a showcase, not machinery: drop it in production.
- The submit is intercepted with preventDefault: for a real POST remove the interception or call a Server Action.
- 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-012.jsonhttps://vibeui.ru/r/combobox-012.jsonКомпонент самодостаточен: один файл, без зависимостей, собственная палитра --vibeui-combobox-012-*. Корень — form, значение живёт в input type="hidden" с настоящим name, поэтому работает обычная отправка, FormData и Server Action: рисованный список сам по себе отправляться не умеет. Подпись и код разведены: options — это пары value и label, в списке код показан мелким моноширинным текстом, а на сервер уезжает именно он. Кнопка отправки выключена, пока ничего не выбрано; обработчик читает FormData с формы и показывает, что реально ушло. Поле фильтра — role="combobox" с aria-controls и aria-activedescendant, список — role="listbox" с aria-selected на строках.

// Идея компонента: рисованный список не умеет отправляться сам. Значение
// живёт в скрытом input с настоящим name, поэтому форма уходит обычным
// submit и работает с FormData, Server Action и без JS-обвязки. Человек
// видит подпись, а на сервер уезжает код — это разные строки, и путать их
// нельзя.
