Button Group

A three-position switch whose middle means "inherit from the project": built on the radiogroup pattern, where arrows move both focus and selection.

# Install and place "buttongroup-018" (Tri State Switch) 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/buttongroup-018.json

Registry item: https://vibeui.ru/r/buttongroup-018.json
Installs to: components/vibeui/buttongroup-018.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 three-position switch whose middle means "inherit from the project": built on the radiogroup pattern, where arrows move both focus and selection.

A three-position switch on the radiogroup pattern: arrows change the selection immediately. Zero dependencies, one file, a client component.

## 3. How to use it
import { Buttongroup018 } from "@/components/vibeui/buttongroup-018"

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-buttongroup-018-* palette — do not swap it for your theme tokens
- role="radiogroup" with aria-checked: without them the three buttons read as three unrelated toggles
- tabIndex=0 only on the selected button — otherwise the group eats three Tab presses
- moving focus after an arrow: without it the selection travels while focus stays behind
- the equal track columns: otherwise the "index × 100%" offset misses the button
- the middle position as a meaningful value rather than "nothing selected" — a radiogroup always has a selection

## 6. You may change
- the set of positions through options
- the initial position through defaultValue
- the accessible group name through label
- the selection callback through onChange and the active text colour through accent

## 7. Rules
- The aria-labelledby id is a hard-coded string: two groups on a page would share it.
- The surface width is computed for three columns: another count needs its own divisor in the CSS.
- The component does not persist anything: saving the setting is your onChange handler's job.
- 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/buttongroup-018.json

https://vibeui.ru/r/buttongroup-018.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в переменных --vibeui-buttongroup-018-*. Клиентский: useState хранит выбранное значение, useRef держит трек, чтобы после стрелки перевести фокус на новую кнопку. Реализован паттерн radiogroup из WAI-ARIA: кнопки с role="radio" и aria-checked, tabIndex=0 только у выбранной, стрелки в обе стороны с переносом по кругу — в radiogroup стрелка меняет выбор, а не только фокус, и это отличает её от toolbar. Подложка одна на группу: ширина равна трети трека, смещение считается как translateX(index * 100%), поэтому колонки обязаны быть равными (grid-template-columns:repeat(3,1fr)).

Component source

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

"use client"

import { useRef, useState } from "react"
import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Buttongroup018Option = {
  id: string
  label: string
}

export type Buttongroup018Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children" | "onChange"
> & {
  options?: Buttongroup018Option[]
  defaultValue?: string
  label?: string
  onChange?: (id: string) => void
  accent?: string
}

// Идея компонента: трёхпозиционный переключатель «включено / по умолчанию /
// выключено», где средняя позиция — не «ничего не выбрано», а осмысленное
// «как в настройках проекта». Реализован не на radio, а на паттерне
// radiogroup из WAI-ARIA: кнопки с role="radio" и aria-checked, стрелки
// сразу переносят и фокус, и выбор (в radiogroup это одно движение, в
// отличие от toolbar), tabIndex=0 стоит только на выбранной кнопке.
