How to implement sub menu of the current route’s children with vue.js and vue router
Posted By: Anonymous
I’m trying to have the navigation on my Vue app to have a main menu up top populated by all the root level routes, and a side menu if the route has any children. Like so:
The current Design I have has the main navigation with routing links on the top with the router-view below. I have been able to get the side menu working so it it only shows up when I choose Travellers and updates the components/content correctly. However I’m having trouble routing things correctly, when I click on one of the links in the sub menu it does not append to the current path. So when I click on View when I’m in localhost/Traveler and click View the url changes to localhost/View/ instead of localhost/Traveler/View. Also the selection on the top menu gets unselected when I choose something in the child menu.
And I cannot get to the pages via something like localhost/Traveler/View only localhost/View
I started rereading the documentation on nested routes as I began making this post and I think I realized that I should be creating an new router at each level which is not something I have done in my code below.
I’m also not sure how to access the children of the current route. I’ve tried to display them like so:
<h2>Route: {{ $route.name }}</h2>
<ul id="example-1">
<li v-for="child in $route.children">
{{ child.name }}
</li>
</ul>
But I get nothing. Should they be passed as Params or something? Or are the not that easily accessible?
Any advice or help will be greatly appreciated.
Root
Contains top Menu-Nav with router links and router-view below.
<template>
<div id="app" class="container-fluid">
<div class="row">
<div style="width:100%">
<nav-menu params="route: route"></nav-menu>
</div>
</div>
<div class="row">
<div>
<router-view></router-view>
</div>
</div>
</div>
</template>
<script>
import NavMenu from './nav-menu'
export default {
components: {
'nav-menu': NavMenu
},
data() {
return {}
}
}
</script>
Top Nav-Menu
Gets populated with the routes
<template>
<nav class="site-header sticky-top py-1">
<div class="container d-flex flex-column flex-md-row justify-content-between">
<a class="nav-item" v-for="(route, index) in routes" :key="index">
<router-link :to="{path: route.path, params: { idk: 1 }}" exact-active-class="active">
<icon :icon="route.icon" class="mr-2" /><span>{{ route.display }}</span>
</router-link>
</a>
</div>
</nav>
</template>
<script>
import { routes } from '../router/routes'
export default {
data() {
return {
routes,
collapsed: true
}
},
methods: {
toggleCollapsed: function (event) {
this.collapsed = !this.collapsed
}
}
}
</script>
Traveler Page/View
Currently the Traveller Page which has a side bar menu and another router view for the content:
<template>
<div id="app" class="container-fluid">
<div class="wrapper">
<traveler-menu params="route: route"></traveler-menu>
<div id="content">
<router-view name="travlerview"></router-view>
</div>
</div>
</div>
</template>
<script>
import TravelerMenu from './traveler-menu'
export default {
components: {
'traveler-menu': TravelerMenu
},
data() {
return {}
}
}
</script>
Side Bar/ Traveler Menu
<template>
<nav id="sidebar">
<div class="sidebar-header">
<h3>Route's Children:</h3>
</div>
<ul class="list-unstyled components">
<li>
<a class="nav-item" v-for="(route, index) in travelerroutes" :key="index">
<router-link :to="{path: route.path, params: { idk: 1 }}" exact-active-class="active">
<icon :icon="route.icon" class="mr-2" /><span>{{ route.display }}</span>
</router-link>
</a>
</li>
</ul>
</nav>
</template>
<script>
import { travelerroutes } from '../../router/travelerroutes'
export default {
data() {
console.log(travelerroutes);
return {
travelerroutes,
collapsed: true
}
},
methods: {
toggleCollapsed: function (event) {
this.collapsed = !this.collapsed
}
}
}
</script>
Routes
import CounterExample from 'components/counter-example'
import FetchData from 'components/fetch-data'
import HomePage from 'components/home-page'
import TestPage from 'components/test-page'
import Travelers from 'components/Traveler/traveler-root'

export const routes = [

]
Traveler Routes (travelerroutes.js)
import TestPage from 'components/test-page'
import ViewTravelers from 'components/Traveler/TravelerPages/view-travelers'
export const travelerroutes = [{

travlerview: ViewTravelers
}
},
{
name: 'Edit',
path: '/Edit',
display: 'Edit', icon: 'list',
components: {
travlerview: ViewTravelers
}
}];
router/index.js
import Vue from 'vue'
import VueRouter from 'vue-router'
import { routes } from './routes'
Vue.use(VueRouter)
let router = new VueRouter({
mode: 'history',
routes
})
export default router
app.js
import Vue from 'vue'
import axios from 'axios'
import router from './router/index'
import store from './store'
import { sync } from 'vuex-router-sync'
import App from 'components/app-root'
import { FontAwesomeIcon } from './icons'
// Registration of global components

Vue.prototype.$http = axios
sync(store, router)
const app = new Vue({
store,
router,
...App
})
export {
app,
router,
store
}
Let me know if you you need anymore details, context or code.
Solution
You don’t need to create new router instances, instead watch the $route
property and create the sidebar nav menu as it changes. You’ll need to pull the child routes from the $router.options.routes
. Here’s an example:
const router = new VueRouter({_x000D_
routes: [{_x000D_
name: 'home',_x000D_
path: '/',_x000D_
component: {_x000D_
template: '<div>Home</div>'_x000D_
}_x000D_
},_x000D_
{_x000D_
name: 'foo',_x000D_
path: '/foo',_x000D_
component: {_x000D_
template: '<div>Foo<router-view></router-view></div>'_x000D_
},_x000D_
children: [{_x000D_
name: 'foo.baz',_x000D_
path: '/baz',_x000D_
component: {_x000D_
template: '<div>Baz</div>'_x000D_
}_x000D_
}, {_x000D_
name: 'foo.tar',_x000D_
path: '/tar',_x000D_
component: {_x000D_
template: '<div>Tar</div>'_x000D_
}_x000D_
}]_x000D_
},_x000D_
{_x000D_
name: 'bar',_x000D_
path: '/bar',_x000D_
component: {_x000D_
template: '<div>Bar<router-view></router-view></div>'_x000D_
},_x000D_
children: [{_x000D_
name: 'bar.zim',_x000D_
path: '/zim',_x000D_
component: {_x000D_
template: '<div>Zim</div>'_x000D_
}_x000D_
}, {_x000D_
name: 'bar.zug',_x000D_
path: '/zug',_x000D_
component: {_x000D_
template: '<div>Zug</div>'_x000D_
}_x000D_
}]_x000D_
}_x000D_

_x000D_
new Vue({_x000D_

$route: function(current) {_x000D_
const route = this.$router.options.routes.find(route => route.path === current.path)_x000D_
_x000D_
if (route && Array.isArray(route.children)) {_x000D_
this.children = route.children_x000D_
} else if (route) {_x000D_
this.children = []_x000D_
}_x000D_
}_x000D_
}_x000D_
})
