Hidden to Start
To set a canvas as "Hidden to Start," select the canvas and then click on the Canvas tab in the right side Properties Panel. There you can check the box next to Hidden to Start.
Show Canvas
Now that your canvas is hidden, it will not be visible on your live site and you must add an action within your site that will "Show" this hidden canvas or it will remain hidden.
You can create the show action as a scroll action or a click action.
As a Click Action
