Survey authors have the ability to divide the survey into sections. Many times sections are used to group questions by topic. Section Titles identify the name of the section while Section Descriptions are helpful to provide additional context for the survey taker.
To add a description, click into the section title. Then, add in the section description.
If additional languages are enabled, be sure to translate the section title and the section description by selecting the language in the drop down and entering the translated text.
The survey description will appear below the survey title and above the first question in the section.
