Is it possible to randomise 2 sets of answer options at the same time? Here is an example:

I would like to randomise the order that the Yes and No options show. So in the image above, options 1 and 2 should randomise, and 3 and 4 should randomise. The Yes options would always be at the top, the No options below it, and Don't know would always stay at the bottom

Not out of the box. Might be possible with some custom javascript, maybe.

But I don't see that this is very helpful anyway. The radonization is there to avoid any bias because respondents click the first item. However, the first item is always "Yes", so the randomization won't help much, in my opinion.

As @holch,
of course, you CAN do this by tayloring.
1. Create two questions of type "equation" to generate two random numbers.
eqRandom1: {if(is_empty(self),rand(1,2),self)}
eqRandom2: {if(is_empty(self),rand(1,2),self)}

2. Now, in your question you taylor the answer options
1: Yes - {if(eqRandom1==1,"Option 1","Option 2")}
2: Yes - {if(eqRandom1==1,"Option 2","Option 1")}
3: No - {if(eqRandom2==1,"Option 1","Option 2")}
4: No - {if(eqRandom2==1,"Option 2","Option 1")}
5: DK/NA

And in your analysis you have restructure a bit by the random numbers.

That's an easy solution without javascript.

Good solution with Limesurvey means.

A little bit dangerous because can't forget that you need to recode the answers depending on the random number, but besides that it should be easy to do so.

To avoid "forgetting" here the other option, the usual one with the "multiple question" and the equation pushed in between.

A. You create your two random numbers.
B. You create a "multiple" question (M3) (which you hide) with the following subquestions
1: Yes - Option 1
2: Yes - Option 2
3: Yes - Option 1
4​​​​​: No - Option 1
5​​​​​: No - Option 2
​​​​​​​6​​​​​: No - Option 1
​​​​​​​
C: You create a question (eqM3) of type equation with the following:
{M3_1=if(eqRandom1==1,"Y","")}
{M3_2="Y"}
{M3_3=if(eqRandom1==2,"Y","")}
{M3_4=if(eqRandom2==1,"Y","")}
{M3_5="Y"}
{M3_6=if(eqRandom2==2,"Y","")}

D. Your final "single" question has the same codes as M3
1: Yes - Option 1
2: Yes - Option 2
​​​​​​​3: Yes - Option 1
4​​​​​: No - Option 1
5​​​​​: No - Option 2
​​​​​​​6​​​​​: No - Option 1
7. DK/NA

E: You set the array filter of this question to M3.

This way you will certainly remember to move the data
