One limitation I’ve noticed is that while you can toggle layer visibility per slide, there isn’t currently a way to filter features within a layer by attribute directly inside StoryMaps.
For example, if you have a golf course map with a single feature layer containing all holes’ tees, fairways, greens, and markers, you cannot filter that layer by “Hole Number” per slide. The only current workarounds are:
It would be extremely useful if StoryMaps allowed authors to define per-slide attribute filters on existing feature layers, similar to the filtering available in ArcGIS Online Map Viewer. This was available in StoryMaps classic.
