嗨，我其实对此很陌生，所以如果我问了一个明显的问题，我很抱歉。实际上，我用vue.js和coreui做了一个网站。问题是我在这个网站上有两种类型的用户(管理员和联系人(。我希望在导航栏中，当联系人登录时，只能查看导航栏上的某些项目。我该如何做到这一点？我一直在看文件，没有发现任何运气。谢谢
以下是我的代码片段：_nav.js
export default {

通过在sidebar.vue 上添加条件渲染和另一个参数来解决问题
这是我的片段：
边栏.vue
<template v-else>
<template v-if="item.meta === 'forAuth' && $auth.isContactPerson() === true">
<SidebarNavItem :classes="item.class">
<SidebarNavLink :name="item.name" :url="item.url" :icon="item.icon" :badge="item.badge" :variant="item.variant"/>
</SidebarNavItem>
</template>
<template v-if="$auth.isAdmin() === true">
<SidebarNavItem :classes="item.class">
<SidebarNavLink :name="item.name" :url="item.url" :icon="item.icon" :badge="item.badge" :variant="item.variant"/>
</SidebarNavItem>
</template>
</template>

}
isAdmin((和isContactperson((是我用来检查用户是管理员还是联系人的函数
