Combobox

Create Option

A combobox that can create: the last row turns the query into a new label, selects it right away and marks it as new.

# Install and place "combobox-005" (Create Option) 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-005.json

Registry item: https://vibeui.ru/r/combobox-005.json
Installs to: components/vibeui/combobox-005.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 that can create: the last row turns the query into a new label, selects it right away and marks it as new.

A combobox that can add what is missing: a "Create …" row appears when there is no exact match, works from the keyboard and puts the value into the list. One file, zero dependencies.

## 3. How to use it
import { Combobox005 } from "@/components/vibeui/combobox-005"

<Combobox005
  label="Issue label"
  options={["Bug", "Enhancement"]}
  createLabel="Create"
  onSelect={(value, created) => console.log(value, created)}
/>

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-005-* palette — do not swap it for your theme tokens
- the create row as role="option" — a side button falls out of the list's keyboard walk
- the exact-match check: without it the list offers to create something that already exists
- the row's position at the very end: at the top it gets hit by accident instead of the first match
- the dashed rule and color that set it apart — creating is not selecting and must not look the same
- the block's own light surface: without it the dark text disappears on the dark catalog card

## 6. You may change
- the starting list through options and the action caption through createLabel
- the new-value marker through newBadge
- the field caption through label, the placeholder through placeholder and the initial value through defaultValue
- the accent color through accent

## 7. Rules
- Created values live only in component state: persist them from onSelect using its second argument.
- The query is only trimmed, not normalized: "Bug" and "bug " become different labels if you drop the case check.
- A long query stretches the create row — add an ellipsis if that matters.
- 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-005.json
https://vibeui.ru/r/combobox-005.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра --vibeui-combobox-005-*. Клиентский: useState держит известный список, список созданного, запрос, значение и курсор. Строка создания добавляется в конец массива строк, только если запрос непустой и точного совпадения нет; она полноценный role="option", поэтому берётся стрелками и Enter, а не отдельной кнопкой мимо клавиатуры. Созданное попадает в known и получает бейдж — человек видит, что список изменился по его вине. aria-selected на строке создания всегда false: выбранным считается только существующее значение. Строка отделена пунктиром и цветом, чтобы её не нажимали вслепую вместо совпадения.

Component source

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

// и Enter, а не отдельной кнопкой мимо клавиатуры.
