How can I include this menu in all my opinions? [Laravel 5]

Good afternoon, I am trying to create a menu from my table, then I want to share it with my view.

Here is what I have tried so far

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;
use App\Menu as menumodel;
class Maincontroller extends Controller
{
    //
    public function __construct()
     {
        $items = menumodel::tree();
        View::make('items', $items);
    }
}

      

        
        
        
      

    

then in my controller (HomeController). I'm doing it

class HomeController extends Maincontroller{}

      

        
        
        
      

    

and then this is my look

@include('public_template.header')
<div class="right_col" role="main">
  <div class="">
    <div class="page-title">
      <div class="title_left">
        <h3>POST <small> Page to demonstrate multilevel menu</small></h3>
      </div>
    </div>
  </div>
</div>
@include('public_template.footer')

      

        
        
        
      

    

In mine public_template.header

I just include public_template.sidebar

here the contentpublic_template.sidebar

 <div id="sidebar-menu" class="main_menu_side hidden-print main_menu">
              <div class="menu_section">
                <h3>General</h3>
                 <ul class="nav side-menu">
                  @foreach($items as $item)
                  <li><a><i class="fa fa-home"></i> Home <span class="fa fa-chevron-down"></span></a>
                    <ul class="nav child_menu">
                      <li><a href="index.html">Dashboard</a></li>
                      <li><a href="index2.html">Dashboard2</a></li>
                      <li><a href="index3.html">Dashboard3</a></li>
                    </ul>
                  </li>
                  @endforeach
                </ul>
              </div>

            </div>

      

        
        
        
      

    

But with my script above I am getting this error

Undefined variable: items (View: D: \ XAMPP \ HTDOCS \ sitestarter \ resources \ view \ public_template \ sidebar.blade.php) (View: D: \ XAMPP \ HTDOCS \ sitestarter \ resources \ view \ public_template \ sidebar.blade. php) (View: D: \ XAMPP \ HTDOCS \ sitestarter \ resources \ view \ public_template \ sidebar.blade.php)

how can i fix this? thanks in advance and sorry for my bad english

ref How to pass data to all views in Laravel 5?

I am following the Dhawal Chada method. But I still can't figure it out.

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class ComposerMenuProvider extends ServiceProvider
{

    public function boot()
    {
        view()->composer(
            'app',
            'App\Http\ViewComposers\MenuComposer'
        );    }


    public function register()
    {
        //
    }
}

      

        
        
        
      

    

Then create MenuComposer

<?php

namespace App\Http\ViewComposers;

use Illuminate\View\View;

    class MenuComposer
    {
        public $menu = [];
        /**
         * 
         *
         * @return void
         */
        public function __construct()
        {

            $this->items = menumodel::tree();

        }

        public function compose(View $view)
        {
            $view->with('items', end($this->items));
        }
    }

      

        
        
        
      

    

and then in app \ config.php add this line

    App\Providers\ComposerMenuProvider::class,

      

        
        
        
      

    

any solution? I still get the same error;
