Expand/collapse content tree
I want that my homepage looks like [this page][1]


  [1]: http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp

The exact elements and functionalities I need are:

1) The frame on the left side should contain tree which can be expanded/collapsed and corresponding content should appear in the frame on the right side each time user clicks on a node.

2) The symbols for inner and leaf nodes needn't be the same as in the example page, but user should be able to differ between them.

I've used Javascript and HTML years ago. So it would be great to get working example. Thanks in advance
