Key-value

#Introduction

The key-value field allows you to interact with one-dimensional JSON object:

use Filament\Forms\Components\KeyValue;

KeyValue::make('meta')

If you’re saving the data in Eloquent, you should be sure to add an array cast to the model property:

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    protected $casts = [
        'meta' => 'array',
    ];

    // ...
}

#Adding rows

An action button is displayed below the field to allow the user to add a new row.

#Setting the add action button’s label

You may set a label to customize the text that should be displayed in the button for adding a row, using the addActionLabel() method:

use Filament\Forms\Components\KeyValue;

KeyValue::make('meta')
    ->addActionLabel('Add property')

As well as allowing a static value, the addActionLabel() method also accepts a function to dynamically calculate it. You can inject various utilities into the function as parameters.

#Customizing the key-value 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:

• addAction()
• deleteAction()
• reorderAction()

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

use Filament\Actions\Action;
use Filament\Forms\Components\KeyValue;
use Filament\Support\Icons\Heroicon;

KeyValue::make('meta')
    ->deleteAction(
        fn (Action $action) => $action->icon(Heroicon::XMark),
    )

The action registration methods can inject various utilities into the function as parameters.
