How to use Pull type questions?

Hey @ibayaso,

How are you doing in this COVID19 period? I believe that with the grace of GOD, you and your country is doing good.

Like you said that you want to learn more about cascading type questions. These types of forms can be made by EXCEL/XML, you can not build these kinds of questions by odk build. I can give you one link which can help you make a pull-type of question.
I am not sure about your question below are two links , I am sure that from these 2 links 1 link will help you .
Here is link1and link2.

If you can clear more about your question or you can put your questionnaire here, we can help you more, when you get a chance, please introduce yourself here.
I’d also encourage you to add a real picture as your avatar because it helps build community!

Best,
