sidemenu component multiple level menu icon does not work properly

[fengdie]

Code:

menus:[
		{
			text: "报表中心",
			iconCls: "fa fa-wpforms",
			state: "closed",
			children: [
				{
					text: '顾客报表',
					iconCls: "fa fa-wpforms",
					children: [
						{
							text: "客户消费明细表",
							code: 'report.customer.product',
						},
						{
							text: '客户治疗明细表',
							code: 'report.customer.cure'
						}
					]
				}
			]
		}
]

Please import CSS files before the 'App' component.

Code:

import 'vx-easyui/dist/themes/default/easyui.css';
import 'vx-easyui/dist/themes/icon.css';
import 'vx-easyui/dist/themes/vue.css';
import Vue from 'vue/dist/vue.js'
import App from './App.vue'
