It outlines adding a checkbox grid with titles, rows (e.g., \"New York\"), and columns (e.g., \"2014\"). The example then builds a `CheckboxGridValidation` to enforce a limit of one response per column, including setting custom help text. Finally, it applies this validation to the checkbox grid, ensuring responses adhere to the set criteria.\n"]]
