What is the most effective way to show additional fields for a spouse in a medical coverage form when a checkbox is selected?

Using a visible when condition to control the display of additional fields for a spouse in a medical coverage form is an effective approach because it allows for a clear and straightforward configuration within the application. By implementing a visible when condition specifically for the spouse section, the application can dynamically show or hide this portion of the form based on the selection of the checkbox. This method ensures that the user interface remains clean and only displays relevant information, which improves the user experience.

This approach not only helps in maintaining a logical flow on the form—displaying spouse-related fields only when applicable—but also simplifies the management of the visibility rules. This makes it easier for future maintenance and updates, as the conditions are clearly defined for that specific section, and can be adjusted without affecting other unrelated parts of the form.

On the other hand, the other options provide less efficient solutions. Adding a condition directly in the checkbox cell may lead to a more cumbersome implementation and does not separate the logic for spouse information clearly. Setting visibility based on whether the checkbox is not blank in its own cell can create confusion within the form's logic. Setting visibility to not blank in the spouse information section itself also might not establish a direct link between the checkbox state and the fields displayed, leading to potential user experience
