You can filter your roadmap to show only the Lanes, Legend colors, or Tags that you want to display. This is a personal filter, and lets you adjust your view of the roadmap. It is not permanent, and your Viewers won’t see the filters that you have applied.
However, if you want to share a filtered view of your roadmap, you can create custom views to share with different audiences. You can also Export your filtered roadmap into a PDF or PNG and create unique views for different audiences.
Both Viewers and Editors can apply personal filters to roadmaps and Master Plans.
