Extending the package

If you want to extend the Html package, you can do the following.

Create a class that extends Html:

<?php

namespace App\Services;

use Spatie\Html\Elements\Div;
use Spatie\Html\Html;

class HtmlExtended extends Html
{
    public function yesNoRadio($name = null, $model = null)
    {
        return Div::create()->addChildren(
            Div::create()->class('form-check form-check-inline')
                ->addChildren($this->radio($name)->class('form-check-input')->id($name.'_yes')->value(1)->checked(old($name) === '1' || $model[$name] === 1))
                ->addChildren($this->label('Yes')->for($name.'_yes')->class('form-check-label'))
        )->addChildren(
            Div::create()->class('form-check form-check-inline')
                ->addChildren($this->radio($name)->class('form-check-input')->id($name.'_no')->value(0)->checked(old($name) === '0' || $model[$name] === 0))
                ->addChildren($this->label('No')->for($name.'_no')->class('form-check-label'))
        );
    }
}

Re-Register the class in the AppServiceProvider:

<?php

namespace App\Providers;

use App\Helpers\HtmlExtended;
use Illuminate\Support\ServiceProvider;
use Spatie\Html\Html;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {
        $this->app->singleton(Html::class, HtmlExtended::class);
    }
}
