</ul>
</div>
<!-- 初始化 Foundation JS -->
<script>
$(document).ready(function() {
$(document).foundation();
})
</script>
</body>
</html>实例解析
.dropdown 类为按钮添加一个向下的箭头符号"图标。
使用按钮或链接的 data-dropdown="id" 属性来打开下拉菜单。
id 值需要与下拉菜单的内容 (id01) 匹配。
在 <div>, <nav>, <ul> 中添加 .f-dropdown 类和 data-dropdown-content 属性来创建下拉菜单的内容。
最后初始化 Foundation JS。
注意: 在小屏幕上，所有的下拉菜单的宽度是100%。
下拉菜单尺寸
使用 .tiny, .small, .medium, .large 或 .mega 来修改下拉菜单的宽度。
注意: 在小屏幕上，所有的下拉菜单的宽度是100%。

</html>下拉菜单边距
可以使用 .content 类为下拉菜单添加内边距：

</ul>
<!-- Initialize Foundation JS -->
<script>
$(document).ready(function() {
$(document).foundation();

</html>其他实例
<div> 下拉菜单中添加多媒体元素：

</html>下拉菜单触发条件
默认情况下，下拉菜单在点击按钮后显示。如果你需要在鼠标移动上去后显示，可以在按钮上使用 data-options="is_hover:true" 属性:
实例
<!DOCTYPE html>

<title>Foundation 实例</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

</html>分割按钮
我们可以在按钮上添加 .split 类来设置一个分割效果的按钮，分割后会在
<span> 元素上生成一个方向向下的图标按钮:
