Absolutely-positioned panels

This is an absolutePanel that uses bottom and right attributes.

It also has draggable = TRUE, so you can drag it to move it around the page.

The slight transparency is due to style = 'opacity: 0.92'.

You can put anything in absolutePanel, including inputs and outputs:

This absolutePanel is docked to the top of the screen using top, left, and right attributes.

Because fixed=TRUE, it won't scroll with the page.
