Introduction

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

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:

use Filament\Forms\Components\Textarea;

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

<UtilityInjection set="formFields" version="5.x">As well as allowing static values, the rows() and cols() methods also accept functions to dynamically calculate them. You can inject various utilities into the functions as parameters.</UtilityInjection>

Autosizing the textarea

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

use Filament\Forms\Components\Textarea;

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

Optionally, you may pass a boolean value to control if the textarea should be autosizeable or not:

use Filament\Forms\Components\Textarea;

Textarea::make('description')
    ->autosize(FeatureFlag::active())

<UtilityInjection set="formFields" version="5.x">As well as allowing a static value, the autosize() method also accepts a function to dynamically calculate it. You can inject various utilities into the function as parameters.</UtilityInjection>

Making the field read-only

Not to be confused with disabling the field, you may make the field "read-only" using the readOnly() method:

use Filament\Forms\Components\Textarea;

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

There are a few differences, compared to disabled():

• 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 saved(false) to prevent this.
• There are no styling changes, such as less opacity, when using readOnly().
• The field is still focusable when using readOnly().

Optionally, you may pass a boolean value to control if the field should be read-only or not:

use Filament\Forms\Components\Textarea;

Textarea::make('description')
    ->readOnly(FeatureFlag::active())

<UtilityInjection set="formFields" version="5.x">As well as allowing a static value, the readOnly() method also accepts a function to dynamically calculate it. You can inject various utilities into the function as parameters.</UtilityInjection>

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:

use Filament\Forms\Components\Textarea;

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

Optionally, you may pass a boolean value to control if the field should disable Grammarly checks or not:

use Filament\Forms\Components\Textarea;

Textarea::make('description')
    ->disableGrammarly(FeatureFlag::active())

<UtilityInjection set="formFields" version="5.x">As well as allowing a static value, the disableGrammarly() method also accepts a function to dynamically calculate it. You can inject various utilities into the function as parameters.</UtilityInjection>

Trimming whitespace

You can automatically trim whitespace from the beginning and end of the textarea value using the trim() method:

use Filament\Forms\Components\Textarea;

Textarea::make('description')
    ->trim()

You may want to enable trimming globally for all textareas, similar to Laravel's TrimStrings middleware. You can do this in a service provider using the configureUsing() method:

use Filament\Forms\Components\Textarea;

Textarea::configureUsing(function (Textarea $component): void {
    $component->trim();
});

Textarea validation

As well as all rules listed on the validation 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:

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:

use Filament\Forms\Components\Textarea;

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

<UtilityInjection set="formFields" version="5.x">As well as allowing static values, the minLength(), maxLength() and length() methods also accept a function to dynamically calculate them. You can inject various utilities into the function as parameters.</UtilityInjection>
