A showcase is a business space that displays example widgets and data that describes a particular scenario to introduce you to certain widgets and highlight functions.
A showcase is a pre-configured space that illustrates a scenario through a number of pages with each page containing one or more widgets. Typically, the showcase is based on a product template although it might feature renamed widgets and pages to support the scenario. Most of the widgets in a showcase contain data that support the scenario. Other widgets provide a description of what you are seeing on the page and how the widgets interrelate. Showcases can be fully functional so that you can use it like a normal space or they might be a demonstration that shows data but does not do anything with it.
You might see showcase business spaces in the list of spaces or in the Space Manager. You can select the showcase space and explore its contents.
