The poll unit admin panel controls have several functions that allow you to test the poll unit's appearance.
Remove controls
If you want to see how the poll unit appears to a respondent, click on the brown eye next to the X in the upper right corner of the control panel. The eye is outlined in orange in the image below.
The controls will disappear until you reload the page.
Draft mode
If you wish to see how a question looks on the page, click the Draft button. The page will reload, and the button will now read Draft ON. Enter a question ID in the Question field and click the > button. The Question field, > button, and Draft button are outlined in orange below.
The page will reload to show you how that question will look in the poll unit on this page. There will be no changes to the page unless you click the Draft button again to show Draft OFF and re-enter the question ID in the Question field, clicking > once more.
Readonly mode
To test the appearance of the poll unit's answers without recording those answers, click the Readonly button.
The page will reload, and the button will now say Readonly On. You may now submit answers to the poll questions to test the poll unit. The answers will not be recorded so that they won’t skew the survey results.
Be sure you take the poll unit out of Readonly mode after testing.
