Step 3: Create Migration Files

Install all Vue dependencies:

npm install

To calling Laravel API routes. You need to install vue-axios. So use run the following command on command prompt:

npm install vue-axios --save

routes/web.php

use App\Http\Controllers\CountryStateController; Route::get('get_countries', [CountryStateController::class, 'getCountries']);
Route::post('get_states', [CountryStateController::class, 'getStates']);

php artisan make:controller CountryStateController

After that, go to app\Http\Controllers and open CountryStateController.php file. Then update the following code into your CountryStateController.php file:

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Country;
use App\Models\State;
class CountryStateController extends Controller
{ /** * Retrieve countries data * * @return void */ public function getCountries() { $data = Country::get(); return response()->json($data); } /** * Retrieve states data * */ public function getStates(Request $request) { $data = State::where('country_id', $request->country_id)->get(); return response()->json($data); }
}

Step 8: Create Vue Component

Next step, go to resources/assets/js/components folder and create a filed called DropdownComponent.vue.

And update the following code into your DropdownComponent.vue. components file:

<template> <div class="container"> <div class="text-center" style="margin: 20px 0px 20px 0px;"> <span class="text-secondary">Laravel 8 vue.js Dependent Dropdown Example</span> </div> <div class="row justify-content-center" style="margin: 20px 0px 20px 0px;"> <div class="col-md-8"> <div class="card"> <div class="card-body"> <div class="form-group"> <label>Select Country:</label> <select class='form-control' v-model='country' @change='getStates()'> <option value='0' >Select Country</option> <option v-for='data in countries' :value='data.id'>{{ data.name }}</option> </select> </div> <div class="form-group"> <label>Select State:</label> <select class='form-control' v-model='state'> <option value='0' >Select State</option> <option v-for='data in states' :value='data.id'>{{ data.name }}</option> </select> </div> </div> </div> </div> </div> </div>
</template>
<script> export default { data(){ return { country: 0, countries: [], state: 0, states: [] } }, methods:{ getCountries: function(){ axios.get('/get_countries') .then(function (response) { this.countries = response.data; }.bind(this)); }, getStates: function() { axios.get('/get_states',{ params: { country_id: this.country } }).then(function(response){ this.states = response.data; }.bind(this)); } }, created: function(){ this.getCountries() } }
</script>

require('./bootstrap');
window.Vue = require('vue');
Vue.component('dropdown-component', require('./components/DropdownComponent.vue').default);
const app = new Vue({ el: '#app',
});

<!doctype html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <meta name="csrf-token" value="{{ csrf_token() }}"/> <title>How to make dependent dropdown with Vue. js and Laravel - Tutsmake.com</title> <link href="https://fonts.googleapis.com/css?family=Nunito:200,600" rel="stylesheet" type="text/css"> <link href="{{ mix('css/app.css') }}" type="text/css" rel="stylesheet"/>

<body>
<div id="app"> <dropdown-component></dropdown-component>
</div>
<script src="{{ mix('js/app.js') }}" type="text/javascript"></script>
</body>
