The module mmm-ui-demo provides a showcase demonstrating the vision and features of mmm-ui and its underlying dependencies (e.g. mmm-bean). To make it short, have a look at content that shows a simple user-interface example that is fully portable. Via UiDemoFx you can run this demo as JavaFx desktop application. In the same way, UiDemoTvm makes the same demo run in any modern browser.
