Can a user select multiple items from a unique value list in the WAB Query widget? Meaning if a field used in the widget has three potential values (i.e. A,B & C), can one of my users select A and B or B and C, instead of just one value? I've tried holding Ctrl or Shift, but haven't been able to get either of them to work in ArcGIS Online and WAB 2.2.
Is there code I can modify to allow it? Or maybe I'm just doing it incorrectly?
I know using Robert Scheitlin, GISP's Enhanced Search Widget might be an option to add/remove selections but for this specific application the Query widget will be the best overall option.
