Basically what I am trying to do is this:
http://djpate.com/portfolio/scrollTop/

But have the menu on the left hand side which floats and when the screen scrolls down the navigation hits the top of the browser window and just stays there, unless I click on anchor 1 and then the screen scrolls back up and the navigation sits in its original position - inline with Anchor 1 heading.

e.g.

Home -> HEADING one
Link2
Link3
Link4


e.g.
Click on Link3 - page scrolls down to link3 heading

Home
Link2
Link3 -> Heading 3
Link4

Does anyone have any examples of how to do this, we have tried a number of options but can't get it to work with a top navigation bar.

Thanks,
Owain.
