laravel-nova-field-dynamic-select's Introduction

Dynamic select field for Laravel Nova (maintained repo)

This field allows you to dynamically fill contents of a select based on values in other dynamic select fields.

Field is based on nova-belongs-to-dependency but instead of selecting model, you can select custom values.

Installation

composer require royduin/laravel-nova-field-dynamic-select

Usage

Class have 2 special methods on top of default Select from Laravel Nova.

dependsOn can take a list of other fields this one depends on.
options can be either an array or a callable.

If its a callable, it will receive array with selected dependency values as first argument and should return an array of items to be shown on the select field.

Example

public function fields(Request $request)
{
    return [
        ID::make()->sortable(),

        DynamicSelect::make('Country', 'country')
            ->options(['US' => 'United States', 'UK' => 'United Kingdom'])
            ->rules('required')
        ,

        DynamicSelect::make('Provider', 'provider')
            ->options(['PR' => 'Premium', 'ST' => 'Standard'])
            ->rules('required')
        ,

        DynamicSelect::make('Product', 'product')
            ->dependsOn(['country', 'provider'])
            ->options(function($values) { 
                if($values['country'] === 'UK' && $values['provider'] === 'PR') {
                    return ['A' => 'Fast shipping', 'B' => 'Normal shipping', 'C' => 'Free shipping'];
                } else {
                    return ['A' => 'Fast shipping', 'B' => 'Normal shipping'];
                }
