    'locales' => [

    ],

    'style' => 'button',

Usage

Nova Language Tool

You can use it as a tool by registering it with Nova. This is typically done in the tools method of the NovaServiceProvider, in app/Providers/NovaServiceProvider.php.

use Digitalcloud\MultilingualNova\NovaLanguageTool;
// ....

public function tools()
{
    return [
        // ...
        new NovaLanguageTool(),
        // ...
    ];
}

Nova Language Field:

You can add Multilingual field which will show languages to your resource.

    use Digitalcloud\MultilingualNova\Multilingual;
    
    // ....
    
    public function fields(Request $request)
    {
        return [
            // ...
            Multilingual::make('Language'),
            // ...
        ];
    }

Note: the field is a virtual field, and it's not required to be a database column. You can consider it as a language switcher input.

In index and detail page, the field will allow you to go to edit form with the selected language. In create and update page, the field allows you to change the language of inputs in the form in easy and direct way.

Model:

We use Spatie laravel translatable

    use Spatie\Translatable\HasTranslations;
    
    // ....
    
    class User extends Model
    {
    
    use HasTranslations;
    
    protected $fillable = ['name'];

    protected $translatable = ['name'];
 
    }

Defining Locales

You can set the source of locales in the config file. Possible options is array or database. In case your language source is array, you need to add allowed languages in the locales array in the config file. When your language source is database, you need to configure the eloquent model of the language table, the column of the language code and the column of the language label.

Alternatively, you can override the config locales using setLocales(...) function:

    use Digitalcloud\MultilingualNova\Multilingual;
    
    // ....
    
    public function fields(Request $request)
    {
        return [
            // ...
            Multilingual::make('Language')->setLocales([
                  'ar' => 'Arabic',
                  'en' => 'English',
                  'de' => 'Deutsch',
            ]),
            // ...
        ];
    }

Displaying Options

This tool allows you to switch between displaying style of the language selector field. Possible displaying options are button, list or mix. By default, the displaying style is button. If the field has a translation of a specific language, the button will be a blue one - primary button, and if no translation available the button will be grey - default button.

If your application supports many languages, this button displaying style is not suitable, so list displaying will be more suitable. With list displaying, locales are grouped in a dropdown list, allowing you to select an option from this list.

Other perfect option for displaying languages, is mix. It allows you to mix between button and list displaying options. For example, if the system supported less than three locales, then they will display as button otherwise list will be selected. This case can be achieved by setting the convert_to_list_after in the config file with 3 or whatever value you want.
