Hello, I have two vertical frames on my webpage. On the left one, I have all the options e.g.- Java Projects C++ Projects Oracle Projects Now I want to put this feature that when I click any of these options (as given above), the frame should look like this: Java Projects ABC DEF C++Projects Oracle Projects That means, onclicking the options on the frame, I should be able to see a sublist under that option. Could anyone please suggest me, how can I do this. Thanks Vibha.
