How to create sub-form from ODK build?


I want to build an form and sub-form in OKD build using on ODK Collect.

In the main form, it's including collumns: Name , sex (male, female), ages (15-25, 25-35,35-45, >45)

If the people in range >45, it will make subform and ask others question.

Thank you


I don't think, subform is available in ODK. However, you can achieve this by using conditional questions for each age group. You need to apply skip logic for the questions are applicable for >45.

I would advise, you to build forms using XLSForm to get more freedom than build.
