In this Tutorial, I am going to share with you how to make dynamic dependent dropdown box using Ajax like When i select category, then sub category select box value should be change. We can't do this stuff without ajax.

So, in this Post i am going to give you full and very simple example of dynamic select box using change event of jquery. This article written in two parts, so it can be easy to understand and if you are beginner then also you can simply perform because this tutorial is from scratch.

In this example i created two tables as listed bellow:



We perform, when we select country from country dropdown, at that moment state dropdown box value will be change like if i select "US" from country select box then in state select box value will be only "US" state.

So, let's follow bellow few step to do it.

Step 1 : Install Laravel Application

we are going from scratch, So we require to get fresh Laravel application using bellow command, So open your terminal OR command prompt and run bellow command:

composer create-project --prefer-dist laravel/laravel blog

Step 2 : Database Configuration

Step 3: Create countries and states Tables

In this step we have to create migration for countries and states table using Laravel 5.3 php artisan command, so first fire bellow command:

php artisan make:migration create_country_state_table

After this command you will find one file in following path database/migrations and you have to put bellow code in your migration file for create categories table.


use Illuminate\Support\Facades\Schema;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Database\Migrations\Migration;

class CreateCountryStateTable extends Migration



* Run the migrations.


* @return void


public function up()


Schema::create('countries', function (Blueprint $table) {





Schema::create('states', function (Blueprint $table) {









* Reverse the migrations.


* @return void


public function down()






Now we require to run migration be bellow command:

php artisan migrate

After create "countries" and "states" tables, we should have some dummy data for testing, So make sure that.

Step 4: Create Route

In this is step we need to create route for form layout file and another one for ajax post request. so open your routes/web.php file and add following route.


Route::get('myform', 'AjaxDemoController@myform');

Route::post('select-ajax', ['as'=>'select-ajax','uses'=>'AjaxDemoController@selectAjax']);

Ok Now we will see last two step in next page, so click on bellow button.
