Dynamic Multilevel Drop-down menu in Yii2

I want to create a dynamic menu with my table (db). I have followed some instructions which are given below:

Table : "menupanal"

Table : "menupanal"

Step 01: I just create a super controller in app\components\Controller.php

Here is the code:

    namespace app\components;

use app\models\MenuPanal;

class Controller extends \yii\web\Controller
{

    public $menuItems = [];

    public function init(){

     $items = MenuPanal::find()
        ->where(['c_type'  => 'MENU'])
        ->orderBy('id')
        ->all();


     $menuItems = [];
     foreach ($items as $key => $value) {
                 $this->menuItems[] = 
                      ['label' => $value['c_name'], 
                          'items'=> [
                              ['label' => $value['c_redirect'], 'url' => ['#']],
                          ],
                      ];    
            }

  parent::init();
}

Step 02: Changed n main layout page:

        echo Nav::widget([
            'options' => ['class' => 'navbar-nav navbar-right'],

            'items' => Yii::$app->controller->menuItems,
        ]);

It is working in only one level. My question::

Question : how can I add multilevel menu using Super controller ?

I am new in Yii2. Helps are highly appreciated.

  1. Create New MenuHelper in Component folder. There is no default component folder. Please create by yourself.

    <?php

namespace app\components;

use app\models\MenuPanel;
use app\models\Zuser;
use app\models\Vwrole;
use app\assets\AppAsset;


class MenuHelper
{

    public static function getMenu()
    {
        $role_id = 1;
        $result = static::getMenuRecrusive($role_id);
        return $result;
    }

    private static function getMenuRecrusive($parent)
    {

        $items = MenuPanel::find()
            ->where(['c_parentid' => $parent])
            ->orderBy('c_sortord')
            ->asArray()
            ->all();

        $result = []; 

        foreach ($items as $item) {
            $result[] = [
                    'label' => $item['c_name'],
                    'url' => ['#'],
                    'items' => static::getMenuRecrusive($item['id']),
                    '<li class="divider"></li>',
                ];
        }
        return $result;
    }

}

  2. in Main Layout Page put the following code

        echo Nav::widget([
        'options' => ['class' => 'navbar-nav navbar-right'],
        'items' => app\components\MenuHelper::getMenu(),

Enjoy Coding!!

You may use nested sets. Look at this extension for Yii: http://www.yiiframework.com/extension/nestedsetbehavior/ and its documentation. All you need to do is component with dynamic creation of menu items array for nested sets.

I found that there is a Yii2 extension version: http://www.yiiframework.com/extension/yii2-nestedsetbehavior/

Good luck
