Textarea

Multiline text input with FormField chrome and optional autosize.

Introduction

Use Textarea for multiline text entry. Bridge UI provides a dedicated Textarea component instead of combining multiline behavior into TextField.

Choose Textarea when users need to enter paragraphs, comments, or other long-form content. It supports rows, optional autosize, and textarea-specific resize behavior. Use TextField for single-line inputs such as names, emails, or search queries.

Import

import { Textarea } from "@bridge-ui/vue/Components/Textarea";

import { Textarea } from "@bridge-ui/react/Components/Textarea";

Basic usage

Set rows to control the initial height. Bind the value with value/onChange in React or v-model in Vue. For uncontrolled usage with an initial value, use defaultValue in React or default-value in Vue.

Sizes

Control the textarea size with the size prop. Available sizes: 2xs, xs, sm, md (default), lg, xl, and 2xl.

Rounded

Use the rounded prop to control border radius. Available values: none, xs, sm, md, lg, xl, 2xl, 3xl, 4xl, and full (defaults vary by component).

Autosize

Enable autosize to grow the textarea as the user types. The native resize handle is disabled when autosize is on.

Validation

Set error and errorMessage to show invalid styling and an error message below the field.

Accessibility

Textarea follows the same FormField accessibility pattern as TextField:

The label is associated with the textarea via htmlFor / id, using controlId.
description and errorMessage are linked through aria-describedby.
When error is true, the textarea receives aria-invalid="true".

Anatomy

Textarea composes FormField around a native <textarea>:

FormField (root)
├── Header — label, optional corner text, required indicator
├── Container — variant shell
│   └── Textarea — native multiline input
└── Footer — description or error message

When autosize is enabled, the textarea height grows with content and the native resize handle is disabled.
