How to hide the language switcher
In the case in which you decide to launch a multilingual survey, you will observe on the welcome page a drop-down menu that permits your respondents to select the language in which they wish to fill in your survey.

One method that we recommend is to edit the corresponding .twig file. Comment {% if aSurveyInfo.alanguageChanger.show == true %} and add {% if %false == true %}
