Hi @cqulihui,

what about having three questions, remove separators between them and write a JavaScript to ensure that two or more options in total are selected? Should it be possible to skip all three questions or not? If not, one way could be to disable the next button until the condition is met.

Hi @fleb,

Thanks very much for your speedy reply.

I use Matrix Table --> Profile, Multiple Answer question, and I want to hide some choices in some positions. For example, if the first row has 4 choices and the second row has only two choices, I can hide the third and fourth choices in the second row.

I had a try but I found that I can only hide the choices in the first row. How can I hide the choices in the second row or even, say, the sixteenth row?

Here is my code:

> jQuery("#" + this.questionId + " .ChoiceRow:first").find("th.c8").hide();

> jQuery("#" + this.questionId + " .ChoiceRow:second").find("th.c8").hide();

> jQuery("#" + this.questionId + " .ChoiceRow:sixteenth").find("th.c8").hide();

How can I find a certain row?

Thanks again.

Hello @cqulihui ,



Paste the below code in the js(OnReady) of the matrix profile question



var that =this;

var r = ["1,2","2,1"];

for(var i=0;i<r.length;i++){

var t1 = parseInt((r[i]).split(",")[0]);

var t2 = parseInt((r[i]).split(",")[1]);

jQuery("#"+this.questionId+" .ChoiceRow:eq("+(t1 - 1)+") .c"+(t2 + 3)+"").hide();

}





You need to only change the var r line. The var r is set in the below format.



var r = ["r1,c1","r1,c2",....,"rn,cn"];



Hence you need to make row and column pair to hide particular choice. So to hide third and fourth choices in the second row the r will be as below



`var r = ["2,3","2,4"];`
