PDF Forms - expanding multi-line text fields

PDF Forms - expanding multi-line text fields

I am composing a document that contains pdf forms. Example code in "Widgets
Uncovered," shows how to specify the height and width of a multi-line text
field. Here is a small example:

\usemodule[fields]
\setupinteraction[state=start]
\setupfield [TextSetup]
[width=\textwidth,height=5em,background=screen,backgroundscreen=.97,frame=off]
\definefield [Block] [text] [TextSetup]
\starttext
   \field [Block]
\stoptext

In this example the height is 5em.  The field will scroll lines up when the
height of the lines typed exceeds the height of the field. Click outside
the field and the field displays the first n-lines that fit within its
height.

My question is, is it possible to tell the field to expand beyond its
initial field height to display all its lines?

A second less pressing question is, is it possible to tell lines to wrap
when they exceed the field width?

With kind regards,
