Ok, so I tried to add the following javascript code, in the question text field. My question id is 426. Unfortunately it didn't work, the day dropdown-box is still visible.
<script type="text/javascript">
$(document).ready(function(){
$('#question426 select.day option[value='1']').attr("selected", "selected");
$('#question426 select.day').hide();
})
</script>Any other suggestion, what I have done wrong?
If it is not working with javascript, would it be possible to change the code in quanda.php? I will have only one survey running, where I need the date question format. After the end of that survey I could change it back. But I am not sure what I have to change, so the date is saved correctly in the database. Any help is greatly appreciated.
