I am trying to build a website following this Tutorial (Building Web Applications Using Node.js) and currently using HTML, ejs, Node.js (+express), yarn and javascript. I would like to integrate some Tabs like How TO - Tabs.

But I am struggeling to control the hiding and showing tabs from the js routing file. I did not find a way to control the tab divs by the express router. Could anyone please help me or point me into a direction?

Thank you.

PS. My plan is to use parts of the existing Node.js and HTML artifacts to build an app using Electron, Web Assembly and Rust. That is why I use all those things, which might seem a bit overkill at first.
