How can I create a question to list down data and further ask details about the data? For example, I want to ask what types of crops are grown and how much land is used to grow each of them.
@pulse_pakistan maybe the matrix question should solve your issue for this. Would you mind going through this support article Creating a question matrix in the Formbuilder for it?
Hi @Kal_Lam, I am preparing for an Android mobile based data collection. In my understanding, the matrix is for Enketo.
This sounds like you have a select_many question, and then want to iterate thru all the options selected - using a repeat group - to answer some followup questions about each option that was selected. Correct?
If so, you can do with using a select_multiple question, followed by a repeat group where the repeat_count is the number of items select, using count-selected() function.
Then, within the repeat group, you can lookup each item that was selected from the list using the selected-at() function, and using the index of the repeat iteration via the position() function.

Once you select the items of interest, the repeat group presents followup questions for each one you selected:
