# Install and place "buttongroup-023" (Text Align Bar) 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-023.json

Registry item: https://vibeui.ru/r/buttongroup-023.json
Installs to: components/vibeui/buttongroup-023.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
Text alignment marked with an underline instead of a fill: the bar grows from the centre and never fights the text below the toolbar.

An alignment toolbar with an underline on the selected segment. Zero dependencies, one file, a server component.

## 3. How to use it
import { Buttongroup023 } from "@/components/vibeui/buttongroup-023"

<Buttongroup023
  defaultValue="start"
  label="Paragraph alignment"
  name="align"
/>

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-023-* palette — do not swap it for your theme tokens
- the underline instead of a fill: the toolbar sits above the text and a coloured block competes with it
- the bar growing via scaleX from the centre — that is what makes the switch read as movement
- the text names under clip-path instead of aria-label: find-in-page can reach them
- radios inside a fieldset: alignment is a single choice and the browser supplies the keyboard
- the distinct icon silhouettes: four identical stacks differ only by the edge they hug

## 6. You may change
- the initial alignment through defaultValue
- the accessible group name through label
- the form field name through name
- the bar and ring colour through accent

## 7. Rules
- The four options are hard-coded: your own set goes into the ALIGNMENTS array.
- The bar rests on the toolbar's bottom border — remove border-bottom and it floats.
- The component aligns nothing: applying it to the text is your editor'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-023.json
https://vibeui.ru/r/buttongroup-023.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в переменных --vibeui-buttongroup-023-*. Серверный: выбор держат radio внутри fieldset. Выбранный сегмент помечен псевдоэлементом ::after — полосой на нижней границе панели, которая появляется через transform:scaleX(0) → scaleX(1) с transform-origin:center, поэтому переключение читается как движение, а не как вспышка. Заливки у активного сегмента нет сознательно: панель стоит над текстом, и цветной прямоугольник спорил бы с ним за внимание. Значки нарисованы «строками текста»: короткая и длинная линии прижаты к нужному краю. Имена вариантов лежат настоящим текстом под clip-path, а не в aria-label — их находит поиск по странице.

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 Buttongroup023Props = Omit<
  ComponentPropsWithoutRef<"fieldset">,
  "children"
> & {
  defaultValue?: string
  label?: string
  name?: string
  accent?: string
}

// Идея компонента: выбор выравнивания помечается не заливкой, а подчёркивающей
// полосой под значком — так группа не спорит с текстом, над которым стоит.
// Полоса растёт из центра через scaleX, поэтому переключение читается как
// движение, а не как вспышка. Значки нарисованы «строками текста»: короткая
// и длинная линии прижаты к нужному краю, и по силуэту видно результат.
// Имена вариантов лежат настоящим текстом под clip-path — их находит поиск
// по странице, в отличие от aria-label.
