Yes; there are some of us who know how to do this.
However it's not so straightforward, and probably doesn't
achieve what you really want to see.

Better is to use a presentation package like TeXPower
(as suggested already).

This does not Show/Hide fields directly.
Instead it allows you to use the same material easily
on multiple pages.

For example, one page has some material typeset nicely,
with a blank region.
The next page has indentical material to the first page, 
but with the blank region now occupied.

A third page may have that extra region blank again,
or occupied by something else, or with some of the words
highlighted, or in a different colour.

With smooth, or perhaps fancy, transitions between the pages
you get the effect of the extra material appearing magically
in place. (You need to view the document in Full-Screen mode
for this effect, otherwise there is an extra refresh that
destroys the smoothness.)


If you really want to show/hide text fields, then you need to
work with embedded JavaScript. The problem with this is that 
are restricted to simple fixed-font text strings within the fields.
You cannot have properly typeset information, such as mathematics.

To explore this route, do a websearch for "AcroTeX" by Donald P. Story.
He recently released a LaTeX package to help do this kind of thing.



Hope this helps,
