# Install and place "buttongroup-026" (Playback Speed) 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-026.json

Registry item: https://vibeui.ru/r/buttongroup-026.json
Installs to: components/vibeui/buttongroup-026.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 playback speed control where the selected segment widens and explains itself in a word while the others shrink to a bare multiplier.

A speed picker whose active segment widens and reveals a caption. Zero dependencies, one file, a server component.

## 3. How to use it
import { Buttongroup026 } from "@/components/vibeui/buttongroup-026"

<Buttongroup026
  speeds={[{ value: "1×", note: "normal" }, { value: "2×", note: "double" }]}
  defaultValue="1×"
  label="Playback speed"
  name="speed"
/>

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-026-* palette — do not swap it for your theme tokens
- animating flex-grow instead of width: the shares always add up to the track and the group never jitters
- flex:1 1 0 with a zero basis — with auto a long caption claims more than half the bar
- hiding the caption with a zero max-width rather than display:none: otherwise there is nothing to animate
- tabular figures on the multipliers: "1.5×" and "1×" would otherwise shift their neighbours
- the prefers-reduced-motion rule — a widening segment is noticeable with vestibular disorders

## 6. You may change
- the speeds and their captions through speeds
- the initial speed through defaultValue
- the accessible group name through label
- the form field name through name and the active text colour through accent

## 7. Rules
- The caption is clipped at max-width:8rem: a long word disappears quietly.
- Beyond five speeds the squeezed segments become narrower than a touch target.
- The component plays nothing: applying the speed is your player'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-026.json
https://vibeui.ru/r/buttongroup-026.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в переменных --vibeui-buttongroup-026-*. Серверный: выбор держат radio внутри fieldset. Приём — анимация flex-grow, а не width: у выбранного сегмента доля растёт до 2.4, сумма долей всегда равна треку, поэтому группа не дрожит и не выезжает за рамку. Пояснение скрыто нулевой max-width с overflow:hidden, а не display:none — так его можно плавно раскрыть. Значения набраны табличными цифрами, все сегменты имеют flex:1 1 0 и min-width:0, иначе «1,5×» забрал бы себе больше «1×». Правило prefers-reduced-motion гасит и переезд, и раскрытие.

Component source

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

import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Buttongroup026Speed = {
  value: string
  note: string
}

export type Buttongroup026Props = Omit<
  ComponentPropsWithoutRef<"fieldset">,
  "children"
> & {
  speeds?: Buttongroup026Speed[]
  defaultValue?: string
  label?: string
  name?: string
  accent?: string
}

// Идея компонента: сегменты не равной ширины — выбранный раздвигается и
// показывает словесное пояснение, остальные ужимаются до множителя. Растёт
// не размер шрифта, а доля во flex: у выбранного flex-grow становится
// больше, и переход анимируется по flex-grow, а не по width, поэтому сумма
// ширин всегда равна треку и группа не дрожит. Пояснение скрыто не
// display:none, а нулевой шириной с overflow:hidden — так его можно плавно
// раскрыть, и оно остаётся в доступном дереве только у выбранного варианта.
