Expanding text in Framemaker

[sulbha bahl]

Hi,
I'm thinking about using expandable text in Framemaker. I have Goggled
and found that other tools can do it, but nothing with FM. Has any one
ever tried it? 

I am creating the chm using Mif2Go and also generating PDF output. Would
expanding text work with CHMS and PDFs?
http://www.indoition.com/en/007.html states Mif2Go has "no built-in
support for some advanced online-help features such as expandable
sections".

All replies appreciated,
Sulbha.
