What happens when the value of a widget with Post On Change enabled is modified?

When the value of a widget with "Post On Change" enabled is modified, the primary function of this feature is to trigger additional functionality in relation to the revised data. The correct understanding of the situation is that modifying the value often leads to a dynamic response in the user interface, which may involve displaying additional fields related to the modified data. This contextual information is essential for the user to understand how their input affects the rest of the form or interface.

The feature allows the application to react in real time to inputs, enhancing the form's interactivity. By displaying additional fields, the system can provide users with the necessary options or information that corresponds to their previous selections, ensuring a more intuitive and user-friendly experience. This interaction fosters a responsive application that adapts to user behavior and needs.

In contrast, other outcomes such as merely refreshing the widget itself or leaving data fields unchanged would not effectively utilize the dynamic capabilities intended by enabling "Post On Change." The goal of such a feature is to offer added information or options that enrich the user's interaction with the application, making the display of additional fields the most appropriate response.
