When you have a multiple choice question in a survey, have you wondered why the data in a popup looks different than in the form?
When Survey123 publishes a single choice question, by default it takes advantage of geodatabase domains to write the default label into the feature layer as well – this allows the label to appear automatically in popups in the Map Viewer and other applications in your ArcGIS Organization.
With multiple choice questions, this is more difficult. Survey123 stores multiple choice questions as comma-separated values in a text field. That means there isn’t a built-in way to view labels for these questions.
