How to implements Nested tree list with doctrine in symfony

Question

I need a Nested tree in my project build on Symfony3 with doctrine. I read this article - link . I understand how it works, but I'm a beginner in symfony and doctrine. So my question is how to implements this in symfony. I've searched for an bundle, which can provide that, but I didn't find any.

My first though was that I will create an entity a than in Controller do what I need (with SQL statemens in doctrine). But I know that it is really bad practice.

So where to store which code? Should I have entity with functions like insertNode, deleteNode (with SQL in it)?

Thanks for advice for best practice on this.
