The Popup Module is an instance that does not contain its own function or status variables. The module can be used as a stylistic means to display objects within a popup.
Several objects belong to a subject group, which should only be viewed quickly when required. In order to display the objects in the popup, they must be copied into the popup instance themselves or via a link.

In the mobile apps, the popup instance has the same representation as a Dummy Module, as these do not allow nesting.
