# Install and place "buttongroup-022" (Zoom Stepper) 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-022.json

Registry item: https://vibeui.ru/r/buttongroup-022.json
Installs to: components/vibeui/buttongroup-022.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 "minus — value — plus" zoom control whose steps follow familiar numbers, with the middle cell returning to one hundred per cent.

A stepped zoom control with the value inside the cluster and a reset on click. Zero dependencies, one file, a client component.

## 3. How to use it
import { Buttongroup022 } from "@/components/vibeui/buttongroup-022"

<Buttongroup022
  steps={[50, 75, 100, 150, 200]}
  defaultValue={100}
  label="Zoom"
  onChange={(zoom) => setZoom(zoom)}
/>

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-022-* palette — do not swap it for your theme tokens
- steps taken from a list of familiar values: an even step turns zooming into a dozen clicks
- the pinned width and tabular figures on the value — otherwise the buttons jump on every step
- disabled at the ends of the range: a live "minus" at minimum zoom is a lie
- aria-label on the icon buttons — a "plus" without a name is announced as "button"
- outline-offset:-2px on focus: an outside ring would be clipped by the container border

## 6. You may change
- the list of values through steps
- the initial and reset value through defaultValue
- the accessible group name through label
- the change callback through onChange and the ring colour through accent

## 7. Rules
- A value missing from steps collapses to the first step: the index is matched exactly.
- The component scales nothing: applying the value is your onChange handler's job.
- The middle cell is clickable and resets the zoom — replace the button with a span if that is unwanted.
- 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-022.json
https://vibeui.ru/r/buttongroup-022.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в переменных --vibeui-buttongroup-022-*. Клиентский: useState хранит текущее значение, шаг двигает индекс по массиву steps. Масштаб идёт не арифметическим шагом, а по списку привычных значений — равномерный шаг в пять процентов заставил бы щёлкать десяток раз. Средняя ячейка — кнопка сброса к defaultValue, у неё min-width:4rem и font-variant-numeric:tabular-nums, поэтому «75 %» и «100 %» занимают одно место. Рамка одна — на контейнере, разделители рисует button + button {border-inline-start}. Крайние значения гасят кнопку через disabled, обводка фокуса уводится внутрь outline-offset:-2px, иначе её срежет рамка контейнера.

Component source

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

"use client"

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

export type Buttongroup022Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children" | "onChange"
> & {
  steps?: number[]
  defaultValue?: number
  label?: string
  onChange?: (zoom: number) => void
  accent?: string
}

// Идея компонента: шаговый регулятор, где значение живёт внутри сцепки
// третьей ячейкой. Масштаб идёт не арифметическим шагом, а по списку
// привычных значений (25, 50, 75, 100…): равномерный шаг в 5 % заставил бы
// щёлкать десяток раз. Средняя ячейка — кнопка сброса к 100 %, у неё
// фиксированная ширина и табличные цифры, иначе «75 %» и «100 %» дёргали бы
// соседей. Крайние значения гасят кнопку через disabled, а не прячут её.
