Node.JS Main menu in the form of a tree

dt65231

Coder
Advise ready-made solutions: on the left the main menu in the form of a tree, on the right the article.
Logic:
- the user clicks on the menu;
- an article corresponding to the menu node appears on the right.
Preferably without updating the entire page, i.e. after clicking on the menu, only a fragment of the page where the article is located is updated.

I suspect you need to use AJAX?
Maybe there are ready-made solutions without bells and whistles?
To click for study.

Note.
Node.I'm studying js.
I have minimal C# experience ASP.NET , MVC.
