In the LIBRARY tab in Public library section you can see already pre-set 1KA example questionnaires and Substantial questionnaires. Within 1KA example questionnaires you can find surveys, forms, quizzes, conditions and filters. You can preview each questionnaire by clicking on the preview (magnifying glass icon) and use them as templates for your survey. To do so, first copy the survey and if desired customize it to your needs.
You can also copy your survey in the library, into My Library sub-tab, and make it more accessible for re-use. You do this by going to the MY SURVEY tab, which provides an overview of all your surveys, and then click on the second-last icon on the far right side of the survey, which you want to copy.
