Is there some documentation about how to add buttons to a story map layout to trigger actions on the map? I would like to recreate functionality similar to the "Tree Location" and "Tree Condition" buttons in the Tree Survey example.
Additionally, could this functionality be incorporated into a drop-down menu in the application to select a layer to show. For instance, I have several polygon layers of demographic data to display underneath a point layer. Instead of having two buttons (like in the Tree Survey example), could those layers be selected from a drop-down list?
Is this supported in any of the templates or does it require customization?
