CSS：

.dropdown-menu .dropdown-menu { position: absolute; top: -9px; left: 100%; } .dropdown-menu li { position: relative; } .dropdown-menu li.hasChildren:before { content: ''; position: absolute; top: 50%; right: 8px; width: 0; height: 0; margin-top: -5px; border-style: solid; border-color: transparent transparent transparent rgba(0, 0, 0, 0.5); border-width: 5px 0 5px 5px; pointer-events: none; } .dropdown-menu li.hasChildren:hover > .dropdown-menu { display: block; }

function initzTreeRightMenu(parentNode) { //树形菜单右击事件 $('li, a', $(parentNode)).contextmenu({ target: '#zTreeRightMenuContainer', //此设置项是zTree的容器 before: function (e, element, target) { //当前右击节点ID var selectedId = element[0].tagName == 'LI' ? element.attr('id') : element.parent().attr('id'); //根据节点ID获取当前节点详细信息 curSelectNode = zTreeObj.getNodeByTId(selectedId); //当前节点的层级 var level = curSelectNode.level; level = 0; //选中当前右击节点 zTreeObj.selectNode(curSelectNode); //根据当前节点层级显示相应的菜单 $('#zTreeRightMenuContainer ul.dropdown-menu[level="' + level + '"]').removeClass('hide').siblings().addClass('hide'); }, onItem: function (context, e) { var action = $(e.target).attr('action'); this.closemenu(); if (action) { zTreeRightMenuFuns[action](); } } });}

步骤：

1、引入zTree相关js、css文件（以我自己的项目为例：jquery.ztree.all-3.5.min.js，zTreeStyle.css）；

2、将上面给出的右键菜单插件另存为js文件引入页面（以我自己的项目为例：bsContextmenu.js）

3、在页面初始化zTree之后，调用上面的方法：initzTreeRightMenu('#schemaMgrTree'); // ‘#schemaMgrTree' 是我自己项目的zTree容器ID

备注：

1、假如zTree中有异步载入的节点（以我自己项目为例：zTree中有部分节点是展开了父节点之后才加载的，像这种情况则需要在 zTree 的 onExpandFun 里面绑定当前节点的子节点）

function onExpandFun(event, treeId, treeNode) { //绑定当前展开节点的子节点右击事件 initzTreeRightMenu('#' + treeNode.tId); //treeNode.tId 是当前展开节点的ID}
