putting expanded text and forms together

[rodeto]

My client wants a site where you can get some info about mortgages. If you click on a question, the answer appears (expanded text) but that expanded text also needs a link in it to a form where people can leave their Name, Phone number and email address to get more info.

If you click that link in the expanded text, the form has to appear in the same place instead of the expanded text.

I have been thinking about this but I cant find a proper solution for that. Is there anyone who can help me with this ?
