Creating Region & Items Dynamically based on SQL Result

Question

Hi,
I need to create regions dynamically during runtime based on SQL.
So the number of regions and title will depends on the SQL result.
I came accross the PLSQL Dynamic Content region type. I searched in the internet, I could not find a matching example.
I looked at the APEX book, it mentions about 'Creating a Matrix of Fields Programmatically' but It's not very descriptive and it's using www_flow_api which i couldn't find documentation about it.
So I am turning into this forum for help.
Can you guys guide me to dynamically create region in a page?
for e.g
If my sql returns 5 records, I need to create 5 regions. Each region will contain a dynamically created tabular form as well depending on another SQL (from table function).
Please let me know if I am not being clear about my question.
Thanks a lot in advance.

hello,
I have the following SQL statement in my region.
SELECT APEX_ITEM.DISPLAY_AND_SAVE(1,rectype) rectype,
       APEX_ITEM.DISPLAY_AND_SAVE(2,class_id) class_id,
       APEX_ITEM.DISPLAY_AND_SAVE(3,attribute_id) attribute_id,
       decode(rectype,1,'<p style="font-size:17px;color:white;background-color:#383838">'||title||'</p>',
                      2,'<p><b><i><big>'||title||'</b></i></big></p>',
                      3,replace(title,chr(13)||chr(10),'</br>'),
                      apex_item.textarea(4,title,5,200)) title,
       decode(rectype,1,'<p style="font-size:17px;color:white;background-color:#383838">'||review1st||'</p>',
                      2,apex_item.text(5,review1st,3,3),
                      3,APEX_ITEM.SELECT_LIST_FROM_LOV(5,review1st,'ARTIST_RANK',null,'NO'),
                      apex_item.hidden(5,review1st)) review1st,
       decode(rectype,1,'<p style="font-size:17px;color:white;background-color:#383838">'||review2nd||'</p>',
                      2,apex_item.text(6,review2nd,3,3),
                      3,APEX_ITEM.SELECT_LIST_FROM_LOV(6,review2nd,'ARTIST_RANK',null,'NO'),
                      apex_item.hidden(6,review2nd)) review2nd
  FROM TABLE (pkg_artist_review.f_artist_review (:P21_ARTIST_SEQ, :P21_ARTIST_DISCIPLINE,:P21_REVIEW_YEAR))as you can see I use DECODE because I need to do HTML formatting on the value and create ITEM according to the value of 'rectype'
decode(rectype,1,'<p style="font-size:17px;color:white;background-color:#383838">'||title||'</p>',
                      2,'<p><b><i><big>'||title||'</b></i></big></p>',
                      3,replace(title,chr(13)||chr(10),'</br>'),
                      apex_item.textarea(4,title,5,200)) title, so the report result would look like
rectype                  title
[display f01]          title
[display f01]          title
[display f01]          title
[display f01]          [text area f04]My question is :
I would think my array list f01 and f04 will have different number of values inside.
f01 will have 4 value, whereas f04 will only have 1.
I tried to use
decode(rectype,1,APEX_ITEM.DISPLAY_AND_SAVE(4,'<p style="font-size:17px;color:white;background-color:#383838">'||title||'</p>'),
                      2,APEX_ITEM.DISPLAY_AND_SAVE(4,'<p><b><i><big>'||title||'</b></i></big></p>'),
                      3,APEX_ITEM.DISPLAY_AND_SAVE(4,replace(title,chr(13)||chr(10),'</br>')),
                      apex_item.textarea(4,title,5,200)) title, I only ended up having the HTML code written to the report.
How can I handle such situation?
I need my array list to have the same number of records thus i could just use one index to iterate through the value.
Thanks in advance.
