==================

I am looking for an Option / Workaround to implement a "other:[free-text]" option within a matrix question.

I usually do it by adding an additional free-text question that filters on given answers for the "Other" option given within the matrix, but this is not sufficient for my design.
Example on how I usually do it: 

Is there a way how I can give the possibility to input text within the sub-questions text, so that respondents have a free-text field after/within "Other:", where they can input text (e.g. Other: "fruit gum") and than rate it within the matrix?


Sorry if this has already been answered somewhere else as I could not find answers. In that case please link me to that thread!

This script in the source of the array will hide the following short-text question and move the input into the last array column label cell:

Thank you that helps a lot!
