        </div>
    <?php endif ?>
//...

View tree.php

<?php
use ale10257\ext\GetTreeWidget;
use yii\helpers\Url;
//Number tree in your Nested Set tree

echo GetTreeWidget::widget([
        'options' => [
            'data' => $data,
            // action for ajax request for edit tree
            'urlChangeTree' => Url::to(['/admin/category/update-tree']),

            'urlAddItem' => Url::to(['/admin/category/create']),
