Question type - Array dual scale/18/en
From LimeSurvey Manual
If enabled, the question will always be hidden - it will not be displayed to the survey participants. This function can be used in the following scenarios:
- If you wish to prefill a question with a URL and you want not to have it displayed on the screen. This overrides any conditions used within the survey because the respective question will not even be embedded on the page.
- If you wish to store or calculate a value on the fly via the Expression Manager.
Note: A common question type that is used with this function is the Equation one.
