I am use bootstrap tagsinput js library for input tags that way it's awesome layout for inputs tags .

Here I will give you full example for laravel tags system tutorial example. So Let's follow bellow step by step.

Step 1 : Install Laravel Fresh App

In first step, You have to need laravel project. You can install laravel fresh project using bellow composer command:

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

Step 2 : Setup Database Configuration

After successfully install laravel app thenafter configure databse setup. We will open ".env" file and change the database name, username and password in the env file.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=Enter_Your_Database_Name
DB_USERNAME=Enter_Your_Database_Username
DB_PASSWORD=Enter_Your_Database_Password

Step 3 : Install rtconner/laravel-tagging Composer Package

In this step, we require to install "rtconner/laravel-tagging" composer package for add tags. so let's run bellow command:

composer require composer require rtconner/laravel-tagging

After successfully install package, open config/app.php file and add service provider.

config/app.php

'providers' => [
    ....
    \Conner\Tagging\Providers\TaggingServiceProvider::class,

]
......

After register provider, we require to make public configuration and then run migration for tags tags, so let's run bellow both command.

php artisan vendor:publish --provider="Conner\Tagging\Providers\TaggingServiceProvider"

For run migration:

php artisan migrate

Step 4 : Create posts table and model

In this step, You have to create posts table in your database. Run bellow command to create migration and modal So lets open terminal and run bellow command:

php artisan make:modal Post -m

After run above command, you will see a migration file in following path database/migrations and you have to simply put following code in migration file to create posts table.

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreatePostsTable extends Migration
{
 /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->longText('description');
            $table->text('tags');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
}

Run migration file and run following command:

php artisan migrate

After create 'posts' table thenafter changes in Post modal copy bellow code and put in the Post.php file.

app/Post.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use App\User;

class Post extends Model
{
    use \Conner\Tagging\Taggable;
    
    protected $fillable = ['title','tags','description'];
}

Step 5 : Add Route

Here We will create route for posts listing and create post. So let's open routes/web.php file and add following routes:

routes/web.php

Route::get('posts', 'PostController@create');
Route::post('posts', 'PostController@store');

Step 6 : Create Controller

In this step, You can create Post Controller and add two method in post controller first method is create form and second method is store data:

app/Http/Controllers/PostController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Post;

class PostController extends Controller
{
    public function create()
    {
        $posts = Post::all();
        return view('posts',compact('posts'));    
    }

    public function store(Request $request)
    {
        $this->validate($request, [
            'title' => 'required',
            'description' => 'required',
            'tags' => 'required',
        ]);

        $input = $request->all();
        $tags = explode(", ", $input['tags']);
        $post = Post::create($input);
        $post->tag($tags);

        return back()->with('success','Post created successfully.');
    }
}

Step 7 : Create View File

In Last step, let's create posts.blade.php(resources/views/posts.blade.php) for layout and we will display all posts and create posts form,so put following code:

resources/views/posts.blade.php
