Usage

Conditional Field

Conditional Field can be used to switch a Field based on other fields values. It use native Nova dependsOn to intercept field changes, the conditions will be resolved in all pages (Index, Detail, Forms).

use Laravel\Nova\Fields\Boolean;
use Laravel\Nova\Fields\FormData;
use Laravel\Nova\Fields\Hidden;
use Laravel\Nova\Fields\Number;
use Laravel\Nova\Fields\Select;
use Laravel\Nova\Fields\Text;
use Laravel\Nova\Http\Requests\NovaRequest;
use Lupennat\Conditionals\Conditional;

class Item extends Resource
{

    public function fields(Request $request)
    {
        return [
            Select::make(__('Type'), 'type')->options([
                'boolean' => 'Boolean',
                'number' => 'Number',
                'not-exists' => 'No Value',
                'text' => 'Text'
            ]),
            Conditional::make(__('Value'))
                ->dependsOn(['type'], function (Conditional $field, NovaRequest $novaRequest, FormData $formData) {
                    return match ($formData->type) {
                        'boolean' => Boolean::make(__('Value'), 'value')->rules('required')
                        'number' => Number::make(__('Value'), 'value')->rules('required', 'min:10', 'max:100'),
                        'text' => Text::make(__('Value'), 'value')->rules('required'),
                        default =>  Hidden::make(__('Value'), 'value')->nullable()->fillUsing(function ($request, $model, $attribute) {
                            // always reset value to null
                            $model->{$attribute} = null;
                        })
                    }
                }),
        ];
    }
}

If you do not want to store/change a value you can return null instead of a field.
When null will be returned an Unfillable Field will be used.

            ConditionalMany::make('Item Value', 'items')
                ->each(
                    function ($item) {
                        return match ($item->type) {

                            default =>  Hidden::make(__('Value'), 'value')
                        }
                    }
                )
        ];
