新问题一个：怎样给下级菜单加alt=""
试了好几次不成功呀！

屁用都没！
看我的一部分代码：
function fwLoadMenus() {
if (window.fw_menu_0) return;
window.fw_menu_0 = new Menu("root",89,21,"Verdana, Arial, Helvetica, sans-serif",14,"#008080","ff0033","#cccccc","#cccccc");
fw_menu_0.addMenuItem("人体艺术","window.open('body.htm', '_blank');");
fw_menu_0.addMenuItem("美女如云","window.open('body.htm', '_blank');");
fw_menu_0.addMenuItem("卡通世界","window.open('body.htm', '_blank');");
fw_menu_0.addMenuItem("自然风光","window.open('body.htm', '_blank');");
fw_menu_0.addMenuItem("楚楚杰作","window.open('body.htm', '_blank');");
fw_menu_0.addMenuItem("贴图特区","window.open('body.htm', '_blank');");
fw_menu_0.bgImageUp="fwmenu1_89x21_up.gif";
fw_menu_0.bgImageOver="fwmenu1_89x21_over.gif";
fw_menu_0.hideonMouseOut=true;

fw_menu_0.writeMenus();
} // fwLoadMenus()

那就用层吧，鼠标一碰，层就显示相应的内容，并且，层的位置在鼠标的旁边。
