I would like to ask my respondents to list the activities they took part in. But, I would like them to fill as many new text boxes as the number of activities they took part it. for example:
Q: please list the activities you took part in
- texbox [as the respondents start filling this textbox, a new one should appear, and so on).
do you know if it is possible?
This exact functionality does not exist. You can use the question type, “Textbox List” to collect multiple text box answers but you have to specify how many rows you want to show the when building.
