Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist arogachev/yii2-tree

or add

"arogachev/yii2-tree": "*"

to the require section of your composer.json file.

Features

• Basic actions with tree nodes: creating, renaming, moving, deleting
• Saving state of nodes (opened / closed)
• Links for updating node

Usage

Add this to application config:

'controllerMap' => [
    'tree' => 'arogachev\tree\controllers\TreeController',
],

Attach additional behavior along with NestedSetsBehavior to your model:

use arogachev\tree\behaviors\NestedSetsManagementBehavior;

/**
 * @inheritdoc
 */
public function behaviors()
{
    return [
        NestedSetsBehavior::className(),
        NestedSetsManagementBehavior::className(),
    ];
}

The last step is display widget:

use arogachev\tree\widgets\NestedSets;
use frontend\modules\department\models\Department;

<?= NestedSets::widget([
    'modelClass' => Department::className(),
]) ?>

Behavior configuration

nameAttribute - string, the name of attribute storing the name of node. Defaults to name.

saveState - boolean, save state of nodes (opened / closed). Defaults to false.

isOpenedAttribute - string, the name of attribute storing if the node opened or closed. Used together with saveState. Defaults to is_opened.

Widget configuration

        'core' => [
            'strings' => [

            ],
        ],
    ],
