## Overview

The textarea allows you to interact with a multi-line string:

```php theme={"theme":"gruvbox-dark-hard"}
use Filament\Forms\Components\Textarea;

Textarea::make('description')
```

## Resizing the textarea

You may change the size of the textarea by defining the `rows()` and `cols()` methods:

```php theme={"theme":"gruvbox-dark-hard"}
use Filament\Forms\Components\Textarea;

Textarea::make('description')
    ->rows(10)
    ->cols(20)
```

### Autosizing the textarea

You may allow the textarea to automatically resize to fit its content by setting the `autosize()` method:

```php theme={"theme":"gruvbox-dark-hard"}
use Filament\Forms\Components\Textarea;

Textarea::make('description')
    ->autosize()
```

## Making the field read-only

Not to be confused with [disabling the field](https://filament-34a8cf01.mintlify.site/3.x/forms/fields/getting-started.md#disabling-a-field), you may make the field "read-only" using the `readOnly()` method:

```php theme={"theme":"gruvbox-dark-hard"}
use Filament\Forms\Components\Textarea;

Textarea::make('description')
    ->readOnly()
```

There are a few differences, compared to [`disabled()`](./getting-started#disabling-a-field):

* When using `readOnly()`, the field will still be sent to the server when the form is submitted. It can be mutated with the browser console, or via JavaScript. You can use [`dehydrated(false)`](../advanced#preventing-a-field-from-being-dehydrated) to prevent this.
* There are no styling changes, such as less opacity, when using `readOnly()`.
* The field is still focusable when using `readOnly()`.

## Disabling Grammarly checks

If the user has Grammarly installed and you would like to prevent it from analyzing the contents of the textarea, you can use the `disableGrammarly()` method:

```php theme={"theme":"gruvbox-dark-hard"}
use Filament\Forms\Components\Textarea;

Textarea::make('description')
    ->disableGrammarly()
```

## Textarea validation

As well as all rules listed on the [validation](https://filament-34a8cf01.mintlify.site/3.x/forms/validation.md) page, there are additional rules that are specific to textareas.

### Length validation

You may limit the length of the textarea by setting the `minLength()` and `maxLength()` methods. These methods add both frontend and backend validation:

```php theme={"theme":"gruvbox-dark-hard"}
use Filament\Forms\Components\Textarea;

Textarea::make('description')
    ->minLength(2)
    ->maxLength(1024)
```

You can also specify the exact length of the textarea by setting the `length()`. This method adds both frontend and backend validation:

```php theme={"theme":"gruvbox-dark-hard"}
use Filament\Forms\Components\Textarea;

Textarea::make('question')
    ->length(100)
```
