<li class="title"><h2>实现方法说明</h2>
<ul class="list">
<li>在 “Demo 演示”中的左侧菜单就是用 zTree 实现的，主要是靠 css 样式负责排版，利用 setting 中的配置进行功能制作，本 Demo 对实现 左侧菜单进行简单的介绍，你也可以通过查看 “Demo 演示”页面的源码深入了解。</li>
<li class="highlight_red">1、关于 css 完全可以根据自己的需要进行个性化调整，例如：此 Demo 的菜单样式 就 与 “Demo 演示”页面的不一样，仅供对比参考</li>
<li class="highlight_red">2、主要用到的配置有：<br/>
setting.view.showIcon / showLine / selectedMulti / dblClickExpand<br/>
setting.callback.onNodeCreated / beforeClick / onClick
</li>
<li>3、是否需要限制单一路径展开，完全由你的需求而定，实现代码可参考 "保持展开单一路径"</li>
<li>4、其他辅助规则，请根据实际情况自行编写</li>
