Hi,

While browsing the forum, I found exactly what I wanted to do here : forums.limesurvey.org/forum/design-issue...oup-and-subquestions
However being a LimeSurvey beginner and not very comfortable with JavaScript, I don't know where to find or how to modify this template.js file.
Could you please help me? My version of LimeSurvey is 3.15.9+190214
Regards,

Hi,
you will not find it, because it is not existing anymore.
The snippet you found was for LimeSurvey version 2.05/2.06.
Since then the structure and the library changed totally.
Now this file is called custom.js

But you can do this easier.

In the question.twig. In your extended theme in theme editor

change these lines

{# Answers #}
{{ include('./subviews/survey/question_subviews/answers.twig') }}

{# Survey question Help #}
{{ include('./subviews/survey/question_subviews/survey_question_help.twig') }}

to
{# Survey question Help #}
{{ include('./subviews/survey/question_subviews/survey_question_help.twig') }}

{# Answers #}
{{ include('./subviews/survey/question_subviews/answers.twig') }}

It worked perfectly. Thank you very much!
