Which action is necessary to ensure all elements in a detail view can be controlled?

To ensure that all elements in a detail view can be controlled effectively, establishing a root object in the PCF (Page Configuration File) is essential. The root object serves as the foundational element for the detail view, providing a context within which all other components, widgets, or elements are organized. By defining a root object, developers can manage the data relationships and display more comprehensively, ensuring that all elements inherit properties and behaviors defined at this higher level.

This structure enables design consistency and simplifies the process of managing properties. It helps in defining how components interact with the data and ensures that changes or updates propagate correctly throughout the component hierarchy. With a clear root object, it becomes easier to control the behavior and appearance of all elements displayed in the detail view, leading to improved maintainability and a better user experience.

The other options, while they may have their own specific uses in web applications, do not provide the comprehensive control needed for all elements within a detail view. For instance, widget inheritance is beneficial for reusing common functionality but does not ensure that all view elements are manageable in the same cohesive manner that a root object does. Similarly, embedding inline styles may address style control but does not assist in managing functional interactions or data binding. Using atomic widgets
