{
    public $leaf;

	public function behaviors() {
		return [
			[
				'class' => ClosureTable::className(),
				'tableName' => 'category_tree'
			],
		];
	}

	public static function find()
	{
		return new CategoryQuery(static::className());
	}
}

Second you need to configure query model as follows:

class CategoryQuery extends ActiveQuery
{
	public function behaviors() {
		return [
			[
				'class' => ClosureTableQuery::className(),

			],
		];
	}
}
