Hi everybody,
I am trying to use the workaround for "Multiple options" question with several primary and secundary options:

However I dont really understand what I have to do in this step:
"Call the function in the source of the question with the question ID (no editing necessary), the start position of the primary sub-question and the number of secondaries to follow. So, in this example, sub-question 1 is a primary followed by 2 secondaries and subquestion 6 is a primary followed by 3 secondaries.

<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
// Sub-question 1 is primary followed by 2 secondaries
secondaryCheckboxes({QID}, 1, 2);
// Sub-question 6 is primary followed by 3 secondaries
secondaryCheckboxes({QID}, 6, 3);
});
</script>

Where excatly do I need to paste this code? And how do I indicated which question in my survey actually is the one with secondary options?

Help is very much appiciated

Usually you need to put this into your question text. From there the {QID} part will be substituted automatically by the actual question id.

However, I am not sure if this works if there is more than one question on the same page. You'll need to test that yourself.

I tried that, but it doesnt work, so I tought I misunderstood. But apparently not.
Is there anything else I need to take care of for it to function?

Can you post a link to where you have the script from and a .lss file?

This is where I got the script manual.limesurvey.org/Workarounds:_Manip..._options.22_question

And this is the Java template I used. At the very end there is the part for the secondary checkbox:
