I am looking for freelancer that will rewrite/port Tree model behaviour to work in Yii2
The reason is that Tree Behaviour from CakePHP is more clean and easy to setup/remove.
Details for required options and the CakePHP behaviour:
http://book.cakephp.org/3.0/en/orm/behaviors/tree.html
http://api.cakephp.org/3.1/class-Cake.ORM.Behavior.TreeBehavior.html
You can PM me
or write here if more details required
