Hi, I'm trying to use this solution in version 3.22.17, but it's not working. I'm attaching an example of the kind of question in which I need to randomize the order of columns.
I tried pasting the function in my theme's "custom.js", and also in the source of the very question (just as you can see in the attached example), but in neither case the columns are randomized.
Any help will be much appreciated!

Elissa asked for randomization of answer options

I would like to randomize answer options in an array question - not subquestions but answers options

Only in arrays the colums are called answer options,
in array(text) or array(number) both scales (x-scale and y-scale) are called subquestions.

So I think this script works is an array, not an array(numbers).

Therefore I changed your question to type "array".

Many thanks Joffm. Unfortunately, switching from Array (Numbers) to Array is not an option in this case, because Array won't let me choose more than one answer per row or column (basically, what I'm trying to do is to join a series of multiple choice questions in a single grid/array).

Hi,
I did not suggest that you change the type of question.
I pointed out that this script is the wrong tool; it has a different purpose. (As you cannot paint your house using a screwdriver)

"array" and "array(numbers)" are totally different things.
In an "array" the database provides one field for each subquestion (row) - there is only one answer per row - but in other arrays, where there is an answer in each cell, the database has to provide a field for each row and each column.

You may read this to find an example for array(number).

The columns can be re-ordered via JavaScript.

Gustavo_Kremer, to avoid confusion, please start a new topic with an appropriate title and attach your sample survey there.

Many thanks to both of you. I'll do that!
