This is the jQuery TreeGrid extension for Yii 2. It encapsulates TreeGrid component in terms of Yii widgets, and thus makes using TreeGrid component in Yii applications extremely easy

Based on leandrogehlen/yii2-treegrid.

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist aadutskevich/yii2-treegrid "*"

or add

"aadutskevich/yii2-treegrid": "*"

to the require section of your composer.json file.

How to use

Model

use yii\db\ActiveRecord;

/**
 * @property string $description
 * @property integer $parent_id
 */
class Tree extends ActiveRecord 
{

    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'tree';
    }  
    
    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['description'], 'required'],
            [['description'], 'string'],
            [['parent_id'], 'integer']
        ];
    }
}

Controller

use yii\web\Controller;
use Yii;
use yii\data\ActiveDataProvider;

class TreeController extends Controller
{

    /**
     * Lists all Tree models.
     * @return mixed
     */
    public function actionIndex()
    {
        $query = Tree::find();
        $dataProvider = new ActiveDataProvider([
            'query' => $query,
        ]);

        return $this->render('index', [
            'dataProvider' => $dataProvider
        ]);
    }

<?= TreeGrid::widget([
        'dataProvider' => $dataProvider,
        'keyColumnName' => 'id',
        'parentColumnName' => 'parent_id',
        'parentRootValue' => '0', //first parentId value
        'pluginOptions' => [
            'initialState' => 'collapsed',
        ],
        'columns' => [
            'name',
            'id',
            'parent_id',
            ['class' => 'yii\grid\ActionColumn']
