// This open/close drop-down menu works by dynamically increasing the //
// vertical size of a spacer image between each main menu item; as    //
// the main items below the nav that is moused-over drop, the         //
// clipping of the layer with the sub-nav items is decreased so that  //
// the sub-nav items show at the same rate that the space increases.  //
//                                                                    //
// In order to allow menu items to completely open or close before    //
// another item begins opening, I've put a layer over the menus while //
// they open/close; the layer has a spacer image and I've turned off  //
// the IE 6 image toolbar for the page.                               //
