Question

我在页面上添加了Superfish Menu jquery插件。我想做的是让它在鼠标上滚动而不是像大多数菜单那样向下滚动。像Windows开始按钮之类的东西。有什么想法吗？

Superfish的默认选项：

$.fn.superfish.defaults = {
  popUpSelector: 'ul,.sf-mega',      // selector within menu context to define the submenu element to be revealed
  hoverClass:    'sfHover',          // the class applied to hovered list items
  pathClass:     'overideThisToUse', // the class you have applied to list items that lead to the current page
  pathLevels:    1,                  // the number of levels of submenus that remain open or are restored using pathClass
  delay:         800,                // the delay in milliseconds that the mouse can remain outside a submenu without it closing
  animation:     {opacity:'show'},   // an object equivalent to first parameter of jQuery’s .animate() method. Used to animate the submenu open
  animationOut:  {opacity:'hide'},   // an object equivalent to first parameter of jQuery’s .animate() method Used to animate the submenu closed
  speed:         'normal',           // speed of the opening animation. Equivalent to second parameter of jQuery’s .animate() method
  speedOut:      'fast',             // speed of the closing animation. Equivalent to second parameter of jQuery’s .animate() method
  cssArrows:     true,               // set to false if you want to remove the CSS-based arrow triangles
  disableHI:     false,              // set to true to disable hoverIntent detection
  onInit:        $.noop,             // callback function fires once Superfish is initialised – 'this' is the containing ul
  onBeforeShow:  $.noop,             // callback function fires just before reveal animation begins – 'this' is the ul about to open
  onShow:        $.noop,             // callback function fires once reveal animation completed – 'this' is the opened ul
  onBeforeHide:  $.noop,             // callback function fires just before closing animation – 'this' is the ul about to close
  onHide:        $.noop,             // callback function fires after a submenu has closed – 'this' is the ul that just closed
  onIdle:        $.noop,             // callback function fires when the 'current' submenu is restored (if using pathClass functionality)
  onDestroy:     $.noop              // callback function fires after the 'destroy' method is called on the menu container
};

所以答案是这样的，来自评论中提到的链接：

您可以创建即插即用风格，而不会干扰核心js功能。所以你要做的第一件事就是：

您必须创建当前superfish.css的新副本

更改以下内容：

.sf-menu ul {
    position: absolute;
    bottom: -999em;
    width: 10em; /* left offset of submenus need to match (see below) */
}

删除此内容：

.sf-menu ul ul {
    top: 0;
    left: 100%;
}

添加以下内容：

.sf-menu li:hover ul,
.sf-menu li.sfHover ul {
    left: 0;
    bottom: 0.0em; /* match top ul list item height */
    z-index: 99;
}
ul.sf-menu li:hover li ul,
ul.sf-menu li.sfHover li ul {
    bottom: -999em;
}
ul.sf-menu li li:hover ul,
ul.sf-menu li li.sfHover ul {
    bottom:-20%; left:100%;
}
ul.sf-menu li li:hover li ul,
ul.UP li li.sfHover li ul {
    top: -999em;
}
ul.sf-menu li li li:hover ul,
ul.sf-menu li li li.sfHover ul {
    left: 10em; /* match ul width */
    top: 0;
}

让你的html菜单看起来像这样。请注意，您正在创建一个div，这将作为您的第一个菜单项的新占位符，因为在步骤1-3中进行的CSS样式更改已将菜单配置为2及以后（请注意climer和icon_image_sml类，这将是在步骤5中用于添加颜色并将外观与菜单的其余部分统一起来：
```
<ul class="sf-menu" id="example">
    <li style='background:transparent;'>
        <div id="climber"><div class="icon_image_sml"></div></div>
        <a href="followed.html">menu item 1</a>
    <ul>
            <li> 
                   (..<and so forth>..)
            </li>
        </ul>
    </li>
</ul>
```

创建一个新的CSS样式表并添加以下内容（这样做样式到第一个菜单项）：

.icon_image_sml {
    display:block;
}

#climber {
    width:40px;
    border-right:1px solid #777;
    height:28px;
    position:absolute;
    left:0px;
    top:0px;
    background-color:#A3B5E5;
}

#ie #climber {
    top:-12px;
}

如果您对css样式有更多了解，请随意对上述参数进行必要的更改，以适应菜单的外观。

像Windows开始按钮一样向上滚动
