Thanks to the different mobile and desktop views, you can easily adapt your graphic creations and content from one version to another.
If you want to integrate some text, a button, an image, etc., on the desktop version that does not appear on the mobile one, or vice-versa:
Right click on the element on the view you would like to make it disappear > "single delete"
The element will then no longer be visible on the relevant view.
Important: this action is not possible on system elements, such as Quiz or Form validation buttons or game elements, such as the visual of the Pinata stick for example.
