Newbie: How to organize dashboards/items?

[pallid herald]

I'm very new to Home Assistant, and followed a guide that added a ProxMox server as a monitored item. Unfortunately, everything is at a single level. I'm watched a couple videos on setting up new dashboards, but not sure of the best way to start to re-organize the mess of items I have already. I was thinking some sort of hierarchy such as:
Home --> Basement Office --> Server --> Host Components
for example but not sure how best to create that? Is that 4 dashboards? Or one dashboard with subelements, etc?

Any pointers to help would be appreciated!

first things first, i would create a new dashboard with the sections layout, its very easy to work with as far as what it provides

I'll do that. Thanks. I just didn't want to get too far in one direction before realizing it was the wrong way to go.

sections are super easy to work with (a little limiting, but not to the point that its not worth the massive improvements in ease of making a good dashboard)

also hacs has a lot of great custom dashboard resources that can help fill the gaps for some stuff

There's really no wrong way. Just different methods and functional capabilities. As you start to get into your design, you may realize that you need to use a different method. It's not hard to "convert" or adapt to a new method.
I started using HA before Sections view; Masonry was the default at the time. I quickly outgrew that and went with a One Panel custom:layout-card design. I still use that method but have also ventured into the YAML Mode dashboard design which is raw YAML code and no UI editor. The custom:layout-card gave me more control over how cards were placed on the screen, while the YAML-based dashboard allows for using ! includes (to place YAML into a separate file and be called) and YAML anchors which is useful for duplicating repetitive code (like shorthand.)
I, personally, don't use the Sections view but do agree that it makes design very easy and is a big improvement over the Masonry view.
