I am not sure if I understand your scenario correctly. Can you please elaborate on it a bit more. And also can you tell me why the approaches described in the links you mentioned don't work for you? I feel I might be missing something from the requirement - "create all three as resizable and expandable zones".
Still I attached a sample solution that I prepared based on your snapshot. Can you have a look at it and let me know if it should be modified to better fit your requirements>
Thank you in advance for your cooperation.
