You can use your Draft survey for templates, or to allow your coworkers or a test audience to take your survey before it's published.
First, create your project or go to an existing project. You don't need to add questions or content yet. The stautus of your survey is indicated by the blue arrows directly under the Page & Survey tab. Surveys are Live by default.
Click the Return to Draft button to change your project to to Draft mode.
The Draft arrow will turn blue, and your survey will no longer be published or viewable by the public.
