There is a dashboard theme for web apps using the web app builder in ArcGIS Online. You can also use operations dashboard. What would you like to be displayed in the dashboard boxes?
I basically just want four maps in four boxes. And what you said whereby these maps can be represented using the ArcGIS dashboard application will suffice.
> ... to create like four dashboard boxes and for each to be controlled when you scroll or zoom in or out from one of them
What do you mean when you say "four dashboard boxes" exactly? Do you mean the app layout has 4 map windows, where when you change the spatial extent of one, it then updates the spatial extents of the other 3 map windows?
Hope this helps,
