The graphical view you want to create must consist of one or more input fields. 

For example, if you want to :

• Install a background image, it will be created with a generic zone 
• Use an image, a button or text that will launch an element, internal or external, it will also be a generic area.
• See a video that loops continuously, whatever its size, it is a video area that will be used 
• Scroll through the content (children) of a section of your application, you will need to choose a content preview area 
• Scroll through images, text or videos that will launch an item, use the carrousel area.
