This command will create the following components on the following path:

app/Http/Livewire/Statecitydropdown.php

resources/views/livewire/statecitydropdown.blade.php

Go to app/Http/Livewire folder and open Statecitydropdown.php file. Then add the following code into your Statecitydropdown.php file:

<?php
  
namespace App\Http\Livewire;
  
use Livewire\Component;
use App\Models\City;
use App\Models\State;
  
class Statecitydropdown extends Component
{
    public $states;
    public $cities;
  
    public $selectedState = NULL;
  
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function mount()
    {
        $this->states = State::all();
        $this->cities = collect();
    }
  
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function render()
    {
        return view('livewire.statecitydropdown')->extends('layouts.app');
    }
  
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function updatedSelectedState($state)
    {
        if (!is_null($state)) {
            $this->cities = City::where('state_id', $state)->get();
        }
    }
