ruoyi vue element 实现点击、返回首页收起已经展开的菜单栏

问题描述

ruoyi VUE菜单有一个BUG，当我们点击其它按钮或者首页的时候，已经展示的一级菜单是不会自动收缩的。这个问题也导致很多开发者把一级菜单都换成了二级菜单。

解决方案 

// src/layout/components/Sidebar/index.vue

<template>
    <div :class="{ 'has-logo': showLogo }"
        :style="{ backgroundColor: settings.sideTheme === 'theme-dark' ? variables.menuBackground : variables.menuLightBackground }">
        <logo v-if="showLogo" :collapse="isCollapse" />
        <el-scrollbar :class="settings.sideTheme" wrap-class="scrollbar-wrapper">
            <el-menu ref="menu" @open="handleOpen" :default-active="activeMenu" :collapse="isCollapse"
                :background-color="settings.sideTheme === 'theme-dark' ? variables.menuBackground : variables.menuLightBackground"
                :text-color="settings.sideTheme === 'theme-dark' ? variables.menuColor : variables.menuLightColor"
                :unique-opened="true" active-text-color="#fff" :collapse-transition="false" mode="vertical">
                <sidebar-item v-for="(route, index) in sidebarRouters" :key="route.path + index" :item="route"
                    :base-path="route.path" />
