For all those looking for the solution, I have found this workaround:
First I have created my array question [Q1].
On a new page (new group), I created a multiple short text question, with the same amount of subquestions as the array question. I have entered the default answer option with the following expression:
Code:
{if(Q1_SQ1 == "ANSWER","manualy add the text of subquestion 1",'')}
This fills the text fields with the desired subquestions if the desired answer is given. If a different answer was chosen, it leaves the field empty.
After that, I hid this question using this
script
Code:
<script type="text/javascript" charset="utf-8">
$('#questionQQ').hide();
</script>
Finally, I have added my next array question. The array filter is chosen for the hidden question. After that, It works like a charm.
