Laravel 6 one --> many relationship in resource controller - php

Question

I currently have an application that can have a modifier with many options. An example use case is a modifier of Toppings with options of cheese, lettuce, salt, and pepper. A modifier can have 1 --> N options.
I want to have a form that displays the Modifier name and also allows the ability to edit/delete Option records at same time. I want to embed this in my current form for adding/editing modifiers.
Is there a simple way to do this so I can have just one Modifier resource controller that also manages Options?
web.php
Route::resource('modifiers', 'ModifierController')->middleware('auth');
Controller:
namespace App\Http\Controllers;
use App\Modifier;
use Illuminate\Http\Request;
class ModifierController extends Controller
{
public function create()
{
$data = ['action' => route('modifiers.store'),'method' => 'POST', 'modifier' => new Modifier()];
return view('modifiers.form',$data);
}
public function store(Request $request)
{
$modifier = new Modifier($request->all());
$this->do_validate($request);
$modifier->save();
return redirect(route('modifiers.index'));
}
}
views/modifiers/form.blade.php
#extends('layouts.layout-2')
#section('content')
<div class="container">
<div class="row justify-content-center">
#include ('layouts.errors')
<div class="col-md-12">
{!! Form::open(['url' => $action, 'method' => 'post', 'class' => 'form', 'id' => 'form'])!!}
#csrf
#method($method)
<div class="form-group">
<label for="name">{{ __('modifiers.name')}}</label>
<input type="text" class="form-control" id="name" name="name" value = "{{old('name',$modifier->name)}}">
</div>
<button id="btnSubmit" class="btn btn-primary">{{ __('common.submit') }}</button>
{!! Form::close() !!}
</div>
</div>
</div>
#endsection
Models:
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Modifier extends Model
{
use SoftDeletes;
protected $guarded = ['id'];
public function options()
{
return $this->hasMany('App\Option');
}
}
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Option extends Model
{
use SoftDeletes;
protected $guarded = ['id'];
public function modifier()
{
return $this->belongsTo('App\Modifier');
}
}

I think you can use a select element:
<select name="options[]" id="options" class="form-control">
#foreach($options as $option)
<option value="{{ $option->id }}" {{ $modifier->options->contains('id', $option->id) ? 'selected' : '' }}>{{ $option->name }}</option>
#endforeach
</select>
Hope it helps.
Then, within some controller:
public function update(Request $request, $id)
{
$modifier = Modifier::find($id);
$modifier->options()->sync($request->input('options'));
// Do whatever more you want to do
}
