				<ul class="list">
				<li>1)、此 Demo 是基于 "高级 增 / 删 / 改 节点" 修改的，并且开放了拖拽功能，可与其进行对比</li>
				<li>2)、只需要同时开启编辑模式和异步加载模式即可实现共存</li>
				<li class="highlight_red">3)、zTree 完善了异步加载模式下的编辑功能，对于未加载子节点的父节点，增加子节点时，会首先进行异步加载。</li>

				<li class="highlight_red">1)、使用 编辑功能，请参考 "拖拽节点基本控制" 和 "基本 增 / 删 / 改 节点" Demo 中关于 setting 的配置要求</li>
