解析：
head头部导入
jquery.multiselect2side.css文件
jquery-1.6.4.min.js jquery文件
jquery.multiselect2side.js文件
**注意：jquery文件必须在jquery.multiselect2side.js之前导入
写一个js调用multiselect2side方法，参数说明
search: "待选区 搜索："参数是添加搜索区
selectedPosition: 'right', 参数是添加右侧的下拉框选择项位置（必须）
moveOptions：移动选项，可以用来给选项排序，实际应用意义不大，这里设置为false
labelsx和labeldx是用来设置左右两个列表框的标题，如果不需要可设置为空
maxSelected：最大选项数，即最多只能选择几项

以上就介绍了jQuery插件实现select下拉框左右选择_交换内容（multiselect2side），包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
