Often when designing a survey, you may need to apply logic or update data without displaying this information to respondents. For this, you can hide a question so that you can use the question for analysis without bothering respondents with additional questions.
Go to: Login » Surveys (select a survey) » Edit » Workspace
This will hide the question from display.
No. Validation for question is not supported if the question is hidden.
