layui tab标签右键关闭菜单，  
包括：关闭当前（closethis）、关闭所有（closeall）、关闭其它（closeothers）、关闭左侧所有（closeleft）、关闭右侧所有（closeright）、刷新当前页（refresh）

--------------------

样式如下：

--------------------

需要 tabrightmenu.js 文末获取

html：

js：

/*选项卡右键关闭刷新*/
    layui.config({ 
    	base: 'js/',
    }).use(['element', 'tabrightmenu'], function() { 
    	let element = layui.element;
    	let rightmenu_ = layui.tabrightmenu;
    
    	// 默认方式渲染全部：关闭当前（closethis）、关闭所有（closeall）、关闭其它（closeothers）、关闭左侧所有（closeleft）、关闭右侧所有（closeright）、刷新当前页（refresh）
    	rightmenu_.render({ 
    		container: '#nav_xbs_tab',
    		filter: 'xbs_tab',
    		navArr: [
    			{ eventName: 'refresh', title: '刷新当前页'},
    	    { eventName: 'closethis', title: '关闭当前页'},
    	    { eventName: 'closeall', title: '关闭所有页'},
    	    { eventName: 'closeothers', title: '关闭其它页'}
    	],
    	});
    });

配置注意事项：

1. ul的id="xbs_tab" 要和lay-filter="xbs_tab" 的一致
       2. container：对应 外层div的id="nav_xbs_tab"
       3. filter：对应 lay-filter="xbs_tab"
