jQuery TreeGrid Extension for Yii 2

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

Installation

The preferred way to install this extension is through composer.

Either run

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

or add

"leandrogehlen/yii2-treegrid": "*"

to the require section of your composer.json file.

Usage

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,
            'pagination' => false
        ]);

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

View

use leandrogehlen\treegrid\TreeGrid;

<?= 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']
    ]     
]); ?>

Adding resources

When is necessary to add other resource files, then should be used the Dependency Injection concept.

To use the saveState option it's necessary to add jquery.cookie.js.

//config/web.php

$config = [
  'id' => 'my-app',
  'components' => [
    ...
  ]
  ...
]

Yii::$container->set('leandrogehlen\treegrid\TreeGridAsset',[
    'js' => [
        'js/jquery.cookie.js',
        'js/jquery.treegrid.min.js',
    ]
]);

return $config;
