Go to the expanded page by clicking the pages selector, and selecting the expanded page from the pop-up menu.
To set up your expanded page:
- Add images, video and other assets by dragging them into the work area, or by using image tags.
- Arrange your images and any other elements you want to use on the stage.
- Be certain that Expanded is selected in the the page's Properties panel.
- Optionally create animations or bring components onto the page.
- If you're creating a Responsive ad or a lightbox ad, add breakpoints, then restyle each new size range.
