Hi Experts,

     I have a requirement to achieve the following layout using List ATS UIBB. i.e with headers and sub-headers. Since I am new to FPM I am not sure if it is possible using the list ATS UIBB or not. If Yes, Could somebody please guide me through the steps to achieve the same.

Thanks & Regards
