Hi,
I've searched the formum and manual and cannot find the solution. I need to ask an array question consisting of several items that all need to be assessed. After assessing all the respondent should choose some, let's say 5, most important items. I would like to have it in one table as in the picture (colors are not important). I was thinking about Multiple question types in array workaround but I'm not sure if I can apply it here. Any advice? Thanks.

I would use a solution similar to this post where we moved input elements from a following question into the array.

In your case the following question would be a multiple-choice type and the input element selector would be "input.text".

Would it be mandatory that 5 check-boxes ar selected?

Thanks Tony, I'll try it. Yes, the 5 check-boxes are mandatory. Or, alternatively, up to 5 check-boxes are mandatory.

Hi Elisa, here's a quick adaptation of that post.

This script moves the check-boxes from a following question into the array and validates for 5 checked boxes.

1) Add this to the question source and modify the error messages as required:
<script type="text/javascript" charset="utf-8">	
 
	$(document).ready(function(){
 
		// The error messages
		var error1 = 'You can only select 5 attributes.';
		var error2 = 'Please select 5 attributes.';
 
		// Identify the questions
		var thisQuestion = $('#question{QID}');
		var nextMultiOpt = $(thisQuestion).nextAll('.multiple-opt:eq(0)');
 
		// Add a class to the array question (for styling) 
		$(thisQuestion).addClass('array-plus-checkboxes');
 
		// Hide the next question 
		$(nextMultiOpt).hide();
 
		// Add an extra column to the array
		$('table.question thead tr', thisQuestion).append('<th class="newColumn1" />');
		$('table.question tbody tr', thisQuestion).each(function(i) {
			$(this).append('<td class="newColumn1" />');
		});
 
		// Move the hidden question text to the inserted column
		$('table.question thead tr th.newColumn1', thisQuestion).text($('.questiontext', nextMultiOpt).text());
 
		// Move the checkboxes into the array
		$('input.checkbox', nextMultiOpt).each(function(i){
			$('table.question tbody tr:eq('+i+') td.newColumn1', thisQuestion).append(this);
		});
 
		// Listener on the checkboxes (to test for maximum 5 checked boxes)
		$('input.checkbox', thisQuestion).click(function(event) {
			if($('input.checkbox:checked', thisQuestion).length > 5) {
				alert(error1);
				$(this).attr('checked', false);
			}
			if($('input.checkbox:checked', thisQuestion).length == 5) {
				$('th.newColumn1', thisQuestion).removeClass('mandatory-error');
			}
		});
 
		// Interrupt the Next/Submit function (to test for minimum 5 checked boxes)
		$('form#limesurvey').submit(function(){
 
			// Override the built-in "disable navigation buttons" feature
			$('#moveprevbtn, #movenextbtn, #movesubmitbtn').attr('disabled', '');
 
			$('th.newColumn1', thisQuestion).removeClass('mandatory-error');
 
			if($('input.checkbox:checked', thisQuestion).length < 5) {
				$('th.newColumn1', thisQuestion).addClass('mandatory-error');
				alert(error2);
				return false;
			}
		});
 
		// Some cleanup styles
		$('col', thisQuestion).css({
			'width': 'auto'
		});
 
	});
</script>

2) Add something like this to the end of template.css:
.array-plus-checkboxes tbody td {
	width: 12%;
}
 
.array-plus-checkboxes td.newColumn1 {
	width: 15%;
}
 
.array-plus-checkboxes .newColumn1 {
	background-color: #FF6;
}
 
.array-plus-checkboxes .newColumn1.mandatory-error {
	color: #FF0000;
}

Tony, you know you are great! It works. Thank you very much. Chapeau bas. I tried to adapt the script myself but I'm too JS illiterate to do that. I wish you all the best in the New Year!

Hello,
I'm coming back with this topic because the solution doesn't seem to work anymore. It worked perfectly in January with the former version of LM but after updating to the current version there is something wrong with it. I can fill in the questions but after pressing the submit key answers are deleted and I get a message of non answered questions. I'm asking for help with correcting this and adapting to the current version of LS.

Hi Elisa,

I am researching the very same question myself and found this in the manual. Whether it applies to LS 2.05+ or not though I would like to find out?

Perhaps you've already seen this yourself. But, I am interested to hear the answer because it would certainly solve a lot of design issues.

Thanks Danika. I think that I've identified the issue - this is the part with interrupting submitting key when less than 5 attributes are checked in the second question (line 44). The other part of the script is OK. The problem is that I'm a java script illiterate and I cannot solve it myself ;-).

Thanks, Elisa.

Please post back to update. These are some of the same challenges I hope to resolve as well.

Cheers
