I think terminology is being mixed and possibly causing some confusion but, I could be wrong.
Regarding the indentation in @neonturbo 's screen example, I believe he just hid the first part of the bedroom and therefore it looks like he indented it further than Hubitat's default.
This would be a correct statement, the Hubitat dashboard doesn't have a hierarchy. However, you can create multiple dashboards representing each room and then link them together to go from one to the other and back. Note that the Hubitat dashboard is IMHO very basic at first but does provide you with the ability to modify the underlying CSS should you need that level of customization otherwise there are other options like
webCore and many other that work on IOS
You can also get some pretty cool tips from the Show Off Your Dashboards! thread for the Hubitat dashboard.
Continue to come back with questions, Hubitat has a fantastic community and support at all levels.
