Or, as a simplified version of that workaround, you could add this to the source of the question. This script will hide all multiple-short-txt answers except the first one and then as a value is entered in each, the next one is shown.
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
$('.multiple-short-txt ul.subquestions-list li').hide();
$('.multiple-short-txt ul.subquestions-list li:first').show();
$('.multiple-short-txt ul.subquestions-list input.text').keyup(function(){
if($(this).val() !== '') {
$(this).parents('li:eq(0)').next('li').show();
}
});
});
</script>
Here's a sample survey with the code in the first question of your group.
