Usage

Basic Usage

use Iamgerwin\NovaDependencyContainer\NovaDependencyContainer;
use Laravel\Nova\Fields\Select;
use Laravel\Nova\Fields\Text;
use Laravel\Nova\Fields\Textarea;

public function fields(NovaRequest $request)
{
    return [
        Select::make('Type')
            ->options([
                'personal' => 'Personal',
                'business' => 'Business',
            ]),

        NovaDependencyContainer::make([
            Text::make('Company Name'),
            Text::make('Tax ID'),
        ])->dependsOn('type', 'business'),

        NovaDependencyContainer::make([
            Text::make('Personal ID'),
            Text::make('Date of Birth'),
        ])->dependsOn('type', 'personal'),
    ];
}

Available Dependency Methods

dependsOn(string $field, $value)

Show container when field equals specific value:

NovaDependencyContainer::make([
    Text::make('Company Name'),
])->dependsOn('type', 'business')

dependsOnIn(string $field, array $values)

Show container when field value is in array:

NovaDependencyContainer::make([
    Text::make('Priority Note'),
])->dependsOnIn('status', ['urgent', 'high'])

dependsOnNot(string $field, $value)

Show container when field does NOT equal value:

NovaDependencyContainer::make([
    Text::make('Cancellation Reason'),
])->dependsOnNot('status', 'active')

dependsOnNotIn(string $field, array $values)

Show container when field value is NOT in array:

NovaDependencyContainer::make([
    Text::make('Additional Info'),
])->dependsOnNotIn('status', ['completed', 'cancelled'])

dependsOnEmpty(string $field)

Show container when field is empty:

NovaDependencyContainer::make([
    Text::make('Default Value'),
])->dependsOnEmpty('custom_value')

dependsOnNotEmpty(string $field)

Show container when field is NOT empty:

NovaDependencyContainer::make([
    Textarea::make('Description'),
])->dependsOnNotEmpty('title')

dependsOnNullOrZero(string $field)

Show container when field is null or zero:

NovaDependencyContainer::make([
    Text::make('Free tier features'),
])->dependsOnNullOrZero('subscription_plan')

Chaining Multiple Dependencies

You can chain multiple dependencies together. ALL conditions must be met:

NovaDependencyContainer::make([
    Text::make('Premium Features'),
    Text::make('Custom Domain'),
])->dependsOn('plan', 'premium')
  ->dependsOnNotEmpty('company_name')
  ->dependsOnNot('status', 'suspended')

Using with Closures

You can pass a closure to dynamically generate fields:

NovaDependencyContainer::make(function () {
    return [
        Text::make('Dynamic Field 1'),
        Text::make('Dynamic Field 2'),
    ];
})->dependsOn('type', 'dynamic')

Apply to Fields (Flat Structure)

Use applyToFields() to apply dependencies without the container wrapper:

NovaDependencyContainer::make([
    Text::make('Field 1'),
    Text::make('Field 2'),
])->dependsOn('type', 'special')
  ->applyToFields()

Adding Dependencies to Regular Fields

You can also add dependencies directly to regular Nova fields using the HasDependencies trait:

use Iamgerwin\NovaDependencyContainer\HasDependencies;
use Laravel\Nova\Fields\Text;

class CustomTextField extends Text
{
    use HasDependencies;
}

// In your Nova resource:
CustomTextField::make('Special Field')
    ->dependsOn('type', 'custom')

                '2' => 'Address',
                '3' => 'Confirmation',
            ]),

Conditional Validation

public function fields(NovaRequest $request)

            ]),

        NovaDependencyContainer::make([
            Text::make('Card Number')
                ->required()
                ->rules('required', 'credit_card'),
            Text::make('CVV')
                ->required()
                ->rules('required', 'digits:3'),
        ])->dependsOn('payment_method', 'credit_card'),

        NovaDependencyContainer::make([
            Text::make('Bank Account')
                ->required(),
            Text::make('Routing Number')
                ->required(),
        ])->dependsOn('payment_method', 'bank_transfer'),

        NovaDependencyContainer::make([
            Text::make('PayPal Email')
                ->required()
                ->rules('required', 'email'),
