What is the function of the 'default-portlet-decorator' property in portlet decorators?

The function of the 'default-portlet-decorator' property is to set a specific decorator as the default for all portlets within an application. This means that when a portlet is created or rendered, it will use the specified default decorator unless a different one is explicitly defined for a specific portlet or instance. By defining a default decorator, developers can ensure a consistent appearance and behavior across multiple portlets, streamlining the user interface and enhancing the user experience.

This property is particularly useful in scenarios where uniformity in design is a priority, as it allows for quick application of styles and layouts. Custom styles can still be applied to individual portlets if needed, but this default setting establishes a common baseline across the application.

The other options do not accurately represent the purpose of the 'default-portlet-decorator.' For instance, adding custom styles to all portlets pertains more to CSS or inline styles rather than the decorator itself. The loading sequence of decorators would involve a different configuration strategy that isn’t managed through this property. Enhancing security features is unrelated, as it does not pertain to UI design or functionality but rather to system integrity and data protection.
