如何在jsTree树上放置一个图标

Question

所以我有一棵jsTree树，我希望我可以把一个孤零零的星星＆＃39;像这样输入图标......

在树的最顶端：

jsTree是jquery插件，提供交互式树。它完全免费，开源并在MIT许可下分发。 jsTree易于扩展，可扩展，可配置，支持HTML＆amp; JSON数据源和AJAX加载。

jsTree在箱型（内容盒或边框）中正常运行，可作为AMD模块加载，并具有内置的移动主题，可进行响应式设计，可轻松定制。它使用jQuery的事件系统，因此对树中各种事件的绑定回调很熟悉且容易。

只需在容器上方添加一个div，如下所示：

<div>
  <img src="star.png">
</div>
<div id="container" role="main" style="height: 430px;">
  <div id="tree" class="jstree jstree-1 jstree-default jstree-default-small" role="tree" aria-multiselectable="true" tabindex="0" aria-activedescendant="/" aria-busy="false" style="height: 430px;">
    <ul class="jstree-container-ul jstree-children jstree-striped" role="group">
      <li role="treeitem" aria-selected="false" aria-level="1" aria-labelledby="/_anchor" aria-disabled="true" aria-expanded="true" id="/" class="jstree-node  jstree-open jstree-last"><i class="jstree-icon jstree-ocl" role="presentation"></i><a class="jstree-anchor  jstree-disabled" href="#" tabindex="-1" id="/_anchor"><i class="jstree-icon jstree-themeicon folder jstree-themeicon-custom" role="presentation"></i>root</a>
        <ul role="group"
        class="jstree-children">
          <li role="treeitem" aria-selected="false" aria-level="2" aria-labelledby="MENU1_anchor" aria-expanded="false" id="MENU1" class="jstree-node  jstree-closed"><i class="jstree-icon jstree-ocl" role="presentation"></i><a class="jstree-anchor" href="#" tabindex="-1" id="MENU1_anchor"><i class="jstree-icon jstree-themeicon folder jstree-themeicon-custom" role="presentation"></i>MENU1</a>
          </li>
          <li role="treeitem" aria-selected="false" aria-level="2" aria-labelledby="MENU2_anchor" aria-expanded="false" id="MENU2" class="jstree-node  jstree-closed jstree-last"><i class="jstree-icon jstree-ocl" role="presentation"></i><a class="jstree-anchor" href="#" tabindex="-1" id="MENU2_anchor"><i class="jstree-icon jstree-themeicon folder jstree-themeicon-custom" role="presentation"></i>MENU2</a>
          </li>
        </ul>
      </li>
    </ul>
  </div>
  <div id="data" style="height: 430px;">
    <div class="content code" style="display: none; height: 430px;">
      <textarea id="code" readonly="readonly"></textarea>
    </div>
    <div class="content folder" style="display: none; height: 430px;"></div>
    <div class="content image" style="display: none; position: relative; height: 430px;">
      <img src="" alt="" style="display:block; position:absolute; left:50%; top:50%; padding:0; max-height:90%; max-width:90%;">
    </div>
    <div class="content default" style="text-align: center; height: 430px; line-height: 430px;">Select a file from the tree.</div>
  </div>
</div>

我没有star.png，但它看起来像这样
