Rails spinoffs - Mar 2007 - sliding down from the top of the viewport

I have an absolutely positioned div which is at the top of my document, but
whose display is ''none''. On certain actions I want this to
slide down. I''d also
like this slide down to start at the top of the viewport instead of the top of
the document. I tried something like this, but it didn''t work. The
element still
slides down from the top of the document.

  var el = $(''foo'');
  var pos = Postition.page(el);
  if( pos[1] < 0 ) {
    el.setStyle({top: Math.abs(pos[1])});
  }
  new Effect.slideDown(el);

Any ideas? If that''s not enough, I can make a quick online example, but
I wanted
to see if anyone had any ideas before I did that though.

This should be
    el.setStyle({top: Math.abs(pos[1]) + ''px''});

I needed the ''px'' bit. Sorry for the confusion.
