Easyui和zTree兩種方式分別實現樹形下拉框

<div class="form-group"> 
 <label>點擊事件：</label> 
 <input id="selectActionType" class="form-control" onfocus="showActionTypeTree()" onclick="showActionTypeTree()" readonly="readonly" style="border-radius:5px;background-color: white;cursor: default;"/> 
 <input type="hidden" name="actionTypeId" id="actionTypeId"/> 
 <div id="actionTreeContent" class="menuContent" style="border-radius:5px;display: none; z-index:9999;position: absolute; border: 1px #CCC solid; background-color:#f9f9f9;"> 
 <ul id="actionTypeTree" class="ztree" style="margin-top:0;height: 200px;overflow: auto"></ul> 
 </div>
