Show and Tell - Dash Bootstrap Components

First question i have is about the navbar and how it can be used to navigate a multi page app. I will refer to the demo layout you have in the documentation.

Lets say in the menu drop down, clicking Entry 1 would display what your current demo layout shows (Heading + Graph). Now clicking Entry 2 would show lets says the dcc upload component and a corresponding dash datatable. Can you show how to code this? How about having tabs within entry 2…is it possible?

The dash Tabs + Subtabs doesnt really work well for what i am looking for. See thread on this here: Dash Tabs and SubTabs
