Too Long; Didn't Read
While I was developing a <a href="https://laravel.com" target="_blank">Laravel</a> web application, as a feature, I had to implement the tree view of an <a href="https://laravel.com/docs/5.4/eloquent" target="_blank">Eloquent</a> Model. What this means is that each model instance can be a parent, sibling or a child of another instance of the same model.
