Designing Advanced cascading data collection questions in Kobotoolbox 2023

Adding Cascading Select Questions
Cascading select questions are sets of questions whose options depend on the response to a previous question. For example, your form may first ask the region where a respondent is from, and then in the next question list only the towns and villages of that region.
Adding sets of cascading select questions to your form can be done by importing them to a draft form in the form builder or adding them manually to an XLS Form and then uploading that file.
