Hi,
something like this?
Use multiple short text with subquestion relevance, e.g.
SQ002: !is_empty(Q1_SQ001)
SQ003: !is_empty(Q1_SQ002)
Always show the next field, if there was something entered.
But you have to create as much subquestions as you expect the maximum answers.
As Jelo said: there is no dynamic option. The database table is created when you activate the survey.
IMO this is the easy version.
There is a work around where you can use a button.

This example is a bit different, and for version 2.50/2.73.
But it may give you an idea,
And as long as you do not tell us the version you are using, ...
Best regards
Joffm
