Refs

[wildfiremedia]

In your blog mentioning "to add self references in the template", you mean this:

TodoMVC that use ref and JSON without hardcode should fit your treeview code.

In my post I am referring to self references using the tag element that represents the component. Basically allow the component template to call itself to create a recursive template.

Similar to this: http://www.syntaxsuccess.com/viewarticle/recursive-treeview-in-angular-2.0
The linked example is Angular 2, but is illustrates the concept.
