Laravel 9 Vue Js Dependent DropDown Tutorial with Example
Follow the below steps and build dependent dropdown with Vue.js and Laravel 9:
- Step 1: Install Laravel 9 App
- Step 2: Connecting App to Database
- Step 3: Create Migration Files
- Step 4: Create Models
- Step 5: NPM Configuration
- Step 6: Add Routes
- Step 7: Create Controller By Command
- Step 8: Create Vue Component

- Step 10: Run Development Server
Step 1: Install Laravel 9 App
In this step, we need to install laravel latest application setup, So open terminal OR command prompt and execute the following command:
composer create-project --prefer-dist laravel/laravel blog
Step 2: Connecting App to Database
After successfully install laravel app, Go to project .env file and set up database credentials:
DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=here database name here DB_USERNAME=here database username here DB_PASSWORD=here database password here
Step 3: Create Migration Files
Next step, we need to run the following command:
php artisan make:migration create_countries_states_table
Now open create_countries_states_table.php migration file from database>migrations and replace up() function with the following code:
<?php use Illuminate\Support\Facades\Schema; use Illuminate\Database\Schema\Blueprint; use Illuminate\Database\Migrations\Migration; class CreateCountriesStatesTable extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::create('countries', function (Blueprint $table) { $table->bigIncrements('id'); $table->string('name'); $table->timestamps(); }); Schema::create('states', function (Blueprint $table) { $table->bigIncrements('id'); $table->integer('country_id'); $table->string('name'); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::dropIfExists('countries'); Schema::dropIfExists('states'); } }
Next, migrate the table using the below command:
php artisan migrate
Step 4: Create Models
Use the following laravel artisan commands to build country and state model inside laravel app:
php artisan make:model Country php artisan make:model State
Step 5: NPM Configuration
We need to setup Vue and install Vue dependencies using NPM. So run the following command on command prompt:
Install all Vue dependencies:
npm install
To calling Laravel API routes. we need to install vue-axios. So use run the following command on command prompt:
npm install vue-axios --save
After installing all dependencies run this command:
npm run watch
Step 6: Add Routes
Next step, go to routes folder and open web.php file and add the following routes into file:
routes/web.php
use App\Http\Controllers\CountryStateController; Route::get('get_countries', [CountryStateController::class, 'getCountries']); Route::post('get_states', [CountryStateController::class, 'getStates']);
Step 7: Create Controller By Command
Next step, open command prompt and run the following command to create a controller by an artisan:
php artisan make:controller CountryStateController
After that, go to app\Http\Controllers
and open CountryStateController.php file. Then update the following code into 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 DropdownComponent.vue. components file:
<template> <div class="container"> <div class="text-center" style="margin: 20px 0px 20px 0px;"> <span class="text-secondary">Laravel 9 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>
Now open resources/assets/js/app.js
and include the FileUpload.vue component like this:app.js
require('./bootstrap'); window.Vue = require('vue'); Vue.component('dropdown-component', require('./components/DropdownComponent.vue').default); const app = new Vue({ el: '#app', });
Step 9: Initialize Vue Components
In this step, navigate to resources/views and create one folder named layouts. Inside this folder create one blade view file named app.blade.php file.
Next, Navigate to resources/views/layouts and open app.blade.php file. Then update the following code into app.blade.php file as follow:
<!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"/> </head> <body> <div id="app"> <dropdown-component></dropdown-component> </div> <script src="{{ mix('js/app.js') }}" type="text/javascript"></script> </body> </html>
Step 10: Run Development Server
Run the following command to start development server:
npm run dev or npm run watch
