good afternoon,
I'm very curious as to how the "Discover the possibilities with ArcGIS StoryMaps!" made by Esri was created 
I'm seeing two navigation bars and would really like to format mine like this. The top navigation is almost for different pages and its not a constant scroll though like "Moving to ArcGIS StoryMaps" is its own page. this is how I would like mine. Did they use Map Series? I've tried that as well but I'm not sure that's what I'm looking for, I really like the look of this example. Is it a collection?
