Hi all,

I have a question regarding conditions for dropdown options. In my set-up I repeat 2 questions multiple times, only unique combinations of options may be answered.
I would like to visualize this by letting options in the second question not reappear. 

For example:
Question 1 has option 1, option 2 and option 3
Question 2 has option 1, option 2 and option 3.
These two questions are repeated several times.

Round 1:  Respondent answers Q1 with opt1 and Q2 with opt2.
Round 2:  Respondent should now be able to:
answer Q1 with opt 1 and Q2 with opt1 or opt 3. or
answer Q1 with op2 or opt3 and Q2 with opt1, opt2, or opt.3

In my survey there will be far more options than in the given example.
I have included a file, in which I have added the script from this forum post. forums.limesurvey.org/forum/can-i-do-thi...dropdown-menu-values
It perfectly works for removing options from drop down questions. But now I'm hoping it can be altered to fix my problem... 

 

Question visualized:

 
I chose option 1 and "ploeg 1".
So in round 2 when option 1 is selected, ploeg 1 should not reappear. Like this:


Note: I spoke of repeating variables... But  they are of course new variables with the same lay-out.

This will take a fair amount of development. You will need to clone the select elements so you can dynamically reset them if answers are changed.

Could you please elaborate somewhat?

I did something which might be in the way of what you have in mind.
