This is about hiding view annotation like Sections, Elevations and Callouts.
You can hide individual annotation by selecting one or more, Right Click > Hide in View > Elements.
This will hide just those selected in this view only. If you have many and many views to do this in it can get a bit tedious. To restore these Hidden Elements you need to use the Reveal Hidden Elements feature found on the View Control Shortcuts Bar.
This mode will display those things that have been hidden and allow you to UnHide them.
Two other methods are possible, one easy and one a bit more involved but also "easy" depending on your definition of easy.
For "easiest", when you print you can choose the Print Setup Option: Hide unreferenced view tags.
This means that for any views that are not currently on a sheet view Revit will not print their corresponding annotation. They are still visible and yes you have to remember to choose this setting but it is "easy" and more or less automatic.
A more involved approach requires a couple things; a view and the use of the "Hide at Scales Coarser Than" parameter, part of each view's instance parameters and found here.
The first step is to create a view, like a floor plan using a ridiculous scale like full size or maybe 6"=1'-0". This view will never fit on paper. Now you can name this view something like: "Ridiculous Scale View to Hide Annotation" (RSVTHA) or maybe something more discreet?
Now you add all your working sections or elevations that you don't want to clutter your document set. When you place these views on your "RSVTHA" view you need to make sure they are using the same value for the "Hide as Scales Coarser Than" parameter. This will prevent the annotation from showing up in any view that uses a coarser scale than 6"=1'-0". If you have some views using this scale then pick the next scale "up" or coarser.
When you are navigating your sections or manipulating where they cut the model you just use the "RSVTHA" and you never have to worry about them showing up where they aren't wanted.
