I'm working on a crowdsource story map and have been using arcgis online assistant to access the json file for additional customization (based on this blog). What I have managed to do so far is add some additional fields, however I haven't been able to add some additional title areas and explanation text. Also is it possible to add a checklist or dropdown menu via this method? Or is that level of customization only possible by downloading the code? I am not sure the organization I am working with has their own web server, so I am currently trying to avoid that second option.
