# Install and place "textarea-003" (Autogrow Textarea) 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/textarea-003.json

Registry item: https://vibeui.ru/r/textarea-003.json
Installs to: components/vibeui/textarea-003.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 field that grows with its text: the layout itself computes the height from an invisible copy of the content, with no scrollHeight measuring and no jitter.

An autogrowing field built on a grid text copy, with no height measuring. One file, zero dependencies, a client component.

## 3. How to use it
import { Textarea003 } from "@/components/vibeui/textarea-003"

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-textarea-003-* palette — do not swap it for your theme tokens
- the grid-and-copy technique: measuring scrollHeight by hand causes jitter and an extra layout on every keystroke
- the trailing space in content:attr(data-value): without it a final empty line is ignored and the field stops growing
- the identical font and line-height on the copy and the field — otherwise the heights diverge and text is clipped
- overflow:hidden and resize:none on the textarea: a scrollbar inside a growing field makes no sense
- the component's own light surface — without it the dark text disappears on a dark page

## 6. You may change
- the caption through label and the placeholder text through placeholder
- the starting height through rows
- the line under the field through hint
- the accent colour through accent

## 7. Rules
- The field grows without limit: long text makes the card very tall — cap it with max-height if that matters.
- The text copy duplicates the content in an attribute: for very large texts that is extra markup weight.
- The border and focus ring live on the wrapper, not the textarea: put your own styles there too.
- 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/textarea-003.json

https://vibeui.ru/r/textarea-003.json

Клиентский компонент: useState хранит текст, который дублируется в data-value на обёртке. Обёртка — grid, textarea и псевдоэлемент ::after с content:attr(data-value) занимают одну ячейку, поэтому высота ячейки всегда равна высоте текста. Копия скрыта visibility:hidden и наследует шрифт и межстрочный интервал — иначе высоты разойдутся. Прокрутка у поля отключена, изменение размера мышью тоже. Палитра в --vibeui-textarea-003-*.

Component source

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

"use client"

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

export type Textarea003Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children" | "onChange"
> & {
  label?: string
  placeholder?: string
  hint?: string
  /** Сколько строк поле занимает, пока пустое. */
  rows?: number
  accent?: string
}

// Идея компонента: поле, которое растёт под текст. Обычный способ —
// измерять scrollHeight и присваивать высоту вручную — даёт дрожание и
// лишний layout на каждом нажатии. Здесь высоту считает сама раскладка:
// обёртка — grid, в той же ячейке лежит невидимая копия текста через
// content:attr(), и textarea просто занимает всю высоту ячейки.
