Perfect, thank you!!

Hi, I am trying to hide or block some boxes in a matrix item like this one, that should look like a correlation matrix, but I am not getting it.
So far, I have set those boxes with a zero by default, but I don't want participants to be able to modify them, so I would like to hide those.
I have been trying with this code, but nothing has changed in the preview:
jQuery("#"+this.questionId+" tr.ChoiceRow:first input[type=text]").prop("disabled",true);


Could any one give me a hand with this? Thank you!!

https://community.qualtrics.com/XMcommunity/discussion/comment/42862#Comment_42862Your code will disable the text boxes in the first row. It doesn't hide anything. To do what you want, you need to define the cells to hide in an object where the keys are the scale points to hide and the values are arrays of rows to hide. Then loop through the object and the arrays within it to hide the contents of the matching scale/row combinations.

Thank you very much for your answer!! However, I am really new to javascript and am not familiar witht coding, so I would be enormously grateful if anyone had done something similar before and could share, so that I could have some code to look after.
Thank you all so much!!
Best
