How to effectively use Navbar to make multiple screens

I am building a customer pannel and using a navigation bar. I am using navbar as a module. On clicking on any nav item it opens another app with the same navbar. But in Single page applications, this navigation bar should not reload. Can we achieve this SPA in retool as well. Currently i see that on clicking on any navbar we can either go to any other app. But i dont want to go to any other app, I want to open that app in my current app only so that nav bar does not rerender.

Try linking it up with a Tabbed container!

But beware, too many components in an app leads to performance issues!

I want to achieve something like this. But i dont think by using tabbed container i will be able to do that. One, there seems to be no option for aligning it vertically instead of horizontally. Second, We cannot add subtabs to it.
