I'm pretty new to Qualtrics and I have some troubles in custom code with Javascript.
In my survey I need to have many drop down lists in the same question; I succeeded in doing this through the Matrix Table, Profile, Drop Down list. The only issue is that the different questions have a different number of possible choices and, editing the scale points, the ones with less choices have a huge number of empty rows. Looking on internet, I found out that I have to use the code " " in order to leave the row empty but I'm not able to hide the row through Javascript. This is the result I have been able to achieve by now:

On Qualtrics community (https://stackoverflow.com/questions/48425329/hiding-certain-choices-in-a-qualtrics-matrix), I found out this code as a way to solve my issue (it was actually related to a side by side question but, as I'm still working with a table, I though it could have been a solution):
{
$('QR~QID1~1~2').up('td').childElements().invoke('hide');
});
Actually the code doesn't work and I'm not able to solve this issue. Moreover, I would need to hide all the blank rows of each question without setting the code for each row, is it possible?
Thank you very much in advance for all your answers,
Claudio
