With the Screen Templates module, you can create your own web and mobile Screen Templates with predefined elements. You can base them on the OutSystems UI Framework Theme or create a new Theme with custom CSS classes. You can immediately publish a Screen created from a Screen Template and show it as part of a demo.
Clone this module, add Screen Templates to a Flow and publish. After that, all developers connected to the environment can create Screens from your new Screen Templates.
