Drop Down Panel script

Drop Down Panel adds a pull down panel to the top of your page that contains external content fetched via Ajax. Visitors click on the protruding button to cause the panel to drop down and reveal its content. Clicking anywhere on the panel again closes it. You can easily customize the height of the Panel, button text (ie: "panel content"), and drop down speed in milliseconds. A plug and play Ajax drop down panel!
