I would look at using regions based on lists.
First region - A,B,C,D
If you click A, then dispaly region 2 - X,Y,Z
If you click X, hten display region 3 - report
Its correct way.
I want clear description about A.Is it hyper link or button or which type of button.
Please tell me.Which one is the best.
Thanks & Regards,
Not sure what you are asking. Do you have an example on Oracle.com
Just do one example in apex.oracle.com
Got into the workspace, but cannot login to the application
accessing your application but for region display you've to use dynamic action on region.
for more refer https://apex.oracle.com/pls/apex/f?p=31517:103:102521270174834::NO
Just did a quick example on page 7
