Introduction

The checkbox list component allows you to select multiple values from a list of predefined options:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        'tailwind' => 'Tailwind CSS',
        'alpine' => 'Alpine.js',
        'laravel' => 'Laravel',
        'livewire' => 'Laravel Livewire',
    ])

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

These options are returned in JSON format. If you're saving them using Eloquent, you should be sure to add an array cast to the model property:

use Illuminate\Database\Eloquent\Model;

class App extends Model
{
    /**
     * [@return](https://github.com/return) array<string, string>
     */
    protected function casts(): array
    {
        return [
            'technologies' => 'array',
        ];
    }

    // ...
}

Setting option descriptions

You can optionally provide descriptions to each option using the descriptions() method. This method accepts an array of plain text strings, or instances of Illuminate\Support\HtmlString or Illuminate\Contracts\Support\Htmlable. This allows you to render HTML, or even markdown, in the descriptions:

use Filament\Forms\Components\CheckboxList;
use Illuminate\Support\HtmlString;

CheckboxList::make('technologies')
    ->options([
        'tailwind' => 'Tailwind CSS',
        'alpine' => 'Alpine.js',
        'laravel' => 'Laravel',
        'livewire' => 'Laravel Livewire',
    ])
    ->descriptions([
        'tailwind' => 'A utility-first CSS framework for rapidly building modern websites without ever leaving your HTML.',
        'alpine' => new HtmlString('A rugged, minimal tool for composing behavior <strong>directly in your markup</strong>.'),
        'laravel' => str('A **web application** framework with expressive, elegant syntax.')->inlineMarkdown()->toHtmlString(),
        'livewire' => 'A full-stack framework for Laravel building dynamic interfaces simple, without leaving the comfort of Laravel.',
    ])

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

Splitting options into columns

You may split options into columns by using the columns() method:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->columns(2)

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

This method accepts the same options as the columns() method of the grid. This allows you to responsively customize the number of columns at various breakpoints.

Setting the grid direction

By default, when you arrange checkboxes into columns, they will be listed in order vertically. If you'd like to list them horizontally, you may use the gridDirection(GridDirection::Row) method:

use Filament\Forms\Components\CheckboxList;
use Filament\Support\Enums\GridDirection;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->columns(2)
    ->gridDirection(GridDirection::Row)

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

Searching options

You may enable a search input to allow easier access to many options, using the searchable() method:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->searchable()

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

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->searchable(FeatureFlag::active())

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

Bulk toggling checkboxes

You may allow users to toggle all checkboxes at once using the bulkToggleable() method:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->bulkToggleable()

Optionally, you may pass a boolean value to control if the checkboxes should be bulk toggleable or not:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->bulkToggleable(FeatureFlag::active())

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

Disabling specific options

You can disable specific options using the disableOptionWhen() method. It accepts a closure, in which you can check if the option with a specific $value should be disabled:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        'tailwind' => 'Tailwind CSS',
        'alpine' => 'Alpine.js',
        'laravel' => 'Laravel',
        'livewire' => 'Laravel Livewire',
    ])
    ->disableOptionWhen(fn (string $value): bool => $value === 'livewire')

<UtilityInjection set="formFields" version="5.x" extras="Option value;;mixed;;$value;;The value of the option to disable.||Option label;;string | Illuminate\Contracts\Support\Htmlable;;$label;;The label of the option to disable.">You can inject various utilities into the function as parameters.</UtilityInjection>

If you want to retrieve the options that have not been disabled, e.g. for validation purposes, you can do so using getEnabledOptions():

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        'tailwind' => 'Tailwind CSS',
        'alpine' => 'Alpine.js',
        'laravel' => 'Laravel',
        'livewire' => 'Laravel Livewire',
        'heroicons' => 'SVG icons',
    ])
    ->disableOptionWhen(fn (string $value): bool => $value === 'heroicons')
    ->in(fn (CheckboxList $component): array => array_keys($component->getEnabledOptions()))

For more information about the in() function, please see the Validation documentation.

Allowing HTML in the option labels

By default, Filament will escape any HTML in the option labels. If you'd like to allow HTML, you can use the allowHtml() method:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technology')
    ->options([
        'tailwind' => '<span class="text-blue-500">Tailwind</span>',
        'alpine' => '<span class="text-green-500">Alpine</span>',
        'laravel' => '<span class="text-red-500">Laravel</span>',
        'livewire' => '<span class="text-pink-500">Livewire</span>',
    ])
    ->searchable()
    ->allowHtml()

Optionally, you may pass a boolean value to control if the options should allow HTML or not:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technology')
    ->options([
        'tailwind' => '<span class="text-blue-500">Tailwind</span>',
        'alpine' => '<span class="text-green-500">Alpine</span>',
        'laravel' => '<span class="text-red-500">Laravel</span>',
        'livewire' => '<span class="text-pink-500">Livewire</span>',
    ])
    ->searchable()
    ->allowHtml(FeatureFlag::active())

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

Integrating with an Eloquent relationship

If you're building a form inside your Livewire component, make sure you have set up the form's model. Otherwise, Filament doesn't know which model to use to retrieve the relationship from.

You may employ the relationship() method of the CheckboxList to point to a BelongsToMany relationship. Filament will load the options from the relationship, and save them back to the relationship's pivot table when the form is submitted. The titleAttribute is the name of a column that will be used to generate a label for each option:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->relationship(titleAttribute: 'name')

```php
use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->disabled()
    ->relationship(titleAttribute: 'name')
```

Customizing the relationship query

You may customize the database query that retrieves options using the modifyOptionsQueryUsing parameter of the relationship() method:

use Filament\Forms\Components\CheckboxList;
use Illuminate\Database\Eloquent\Builder;

CheckboxList::make('technologies')
    ->relationship(
        titleAttribute: 'name',
        modifyQueryUsing: fn (Builder $query) => $query->withTrashed(),
    )

<UtilityInjection set="formFields" version="5.x" extras="Query;;Illuminate\Database\Eloquent\Builder;;$query;;The Eloquent query builder to modify.">The modifyQueryUsing argument can inject various utilities into the function as parameters.</UtilityInjection>

Customizing the relationship option labels

If you'd like to customize the label of each option, maybe to be more descriptive, or to concatenate a first and last name, you could use a virtual column in your database migration:

$table->string('full_name')->virtualAs('concat(first_name, \' \', last_name)');

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('authors')
    ->relationship(titleAttribute: 'full_name')

Alternatively, you can use the getOptionLabelFromRecordUsing() method to transform an option's Eloquent model into a label:

use Filament\Forms\Components\CheckboxList;
use Illuminate\Database\Eloquent\Builder;
use Illuminate\Database\Eloquent\Model;

CheckboxList::make('authors')
    ->relationship(
        modifyQueryUsing: fn (Builder $query) => $query->orderBy('first_name')->orderBy('last_name'),
    )
    ->getOptionLabelFromRecordUsing(fn (Model $record) => "{$record->first_name} {$record->last_name}")

<UtilityInjection set="formFields" version="5.x" extras="Eloquent record;;Illuminate\Database\Eloquent\Model;;$record;;The Eloquent record to get the option label for.">The getOptionLabelFromRecordUsing() method can inject various utilities into the function as parameters.</UtilityInjection>

Customizing the relationship option descriptions

If you'd like to customize the description of each option, you can use the getOptionDescriptionFromRecordUsing() method to transform an option's Eloquent model into a description:

use Filament\Forms\Components\CheckboxList;
use Illuminate\Database\Eloquent\Builder;
use Illuminate\Database\Eloquent\Model;

CheckboxList::make('authors')
    ->relationship(
        modifyQueryUsing: fn (Builder $query) => $query->orderBy('first_name')->orderBy('last_name'),
    )
    ->getOptionDescriptionFromRecordUsing(fn (Model $record) => $record->notes)

<UtilityInjection set="formFields" version="5.x" extras="Eloquent record;;Illuminate\Database\Eloquent\Model;;$record;;The Eloquent record to get the option description for.">The getOptionDescriptionFromRecordUsing() method can inject various utilities into the function as parameters.</UtilityInjection>

Saving pivot data to the relationship

If your pivot table has additional columns, you can use the pivotData() method to specify the data that should be saved in them:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('primaryTechnologies')
    ->relationship(name: 'technologies', titleAttribute: 'name')
    ->pivotData([
        'is_primary' => true,
    ])

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

Setting a custom no search results message

When you're using a searchable checkbox list, you may want to display a custom message when no search results are found. You can do this using the noSearchResultsMessage() method:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->searchable()
    ->noSearchResultsMessage('No technologies found.')

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

Setting a custom search prompt

When you're using a searchable checkbox list, you may want to tweak the search input's placeholder when the user has not yet entered a search term. You can do this using the searchPrompt() method:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->searchable()
    ->searchPrompt('Search for a technology')

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

Tweaking the search debounce

By default, Filament will wait 1000 milliseconds (1 second) before searching for options when the user types in a searchable checkbox list. It will also wait 1000 milliseconds between searches if the user is continuously typing into the search input. You can change this using the searchDebounce() method:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->searchable()
    ->searchDebounce(500)

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

Customizing the checkbox list action objects

This field uses action objects for easy customization of buttons within it. You can customize these buttons by passing a function to an action registration method. The function has access to the $action object, which you can use to customize it. The following methods are available to customize the actions:

• selectAllAction()
• deselectAllAction()

Here is an example of how you might customize an action:

use Filament\Actions\Action;
use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->selectAllAction(
        fn (Action $action) => $action->label('Select all technologies'),
    )

<UtilityInjection set="formFields" version="5.x" extras="Action;;Filament\Actions\Action;;$action;;The action object to customize.">The action registration methods can inject various utilities into the function as parameters.</UtilityInjection>
