Hi Edson,

There is currently no option to hide network elements that are not connected.
However, there is an option to only show the elements from a given view.

You can create a view and add only the elements you'd like to see in the ip network explorer app to this view.

(note that one element can exist in multiple views, so you can add it to a new view while also keeping it in it's current view).

To filter the nodes in the app, you need to edit the app and change the view filter variable.
