Child select field for Laravel Nova

This field allows you to dynamically fill options of the select based on value in parent select field.

Works with Nova Tabs!

Field is based on nova-ajax-select. But instead of providing api endpoint, you can fill options by a closure function.

Install

composer require amidesfahani/nova-child-select

Usage

Class have 2 special methods on top of default Select from Laravel Nova. parent should be a select field or another child select this one depends on. options should be a callable. it will receive parent select field's value as first argument and should return an array to be shown on the child select field.

Example

public function fields(Request $request)
    {
        return [

            ID::make()->sortable(),

            Select::make('Country')
                ->options(Country::all()->mapWithKeys(function ($country) {
                    return [$country->id => $country->name];
                }))
                ->rules('required'),
