How to read WD_SELECT_OPTIONS_20, Maximum Number of Results checkbox selection?

Hi Experts,

I am using the WD_SELECT_OPTIONS_20 standard component for the select options. I am enabling the 'Maximum Number of Results' option.

I am able to read the number that the user entered. However, I am not sure how to read the checkbox selection. I am calling the  get_input_complete method of the select option handler IF_WD_GROUPED_SELOPT_20.

Thanks,
