Yes, I have; but it's not on the XSLT layer, it's in Javascript in the 
output (HTML) file.

The XSLT generates the HTML from XML source, but the collapse/expand 
functionality is provided by DOM/CSS/Javascript code which is not executed 
by the XSLT engine, but rather by the receiving application (the browser). 
To the XSLT engine, the Javascript is just a chunk of text that is included 
in a <script> node copied by the stylesheet into the result.

Likewise, I would look at doing this in Javascript in the client.

Design your solution in a mockup, using Javascript; then use XSLT to 
transform your XML into that form.

Cheers,
Wendell
