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 ponents/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.

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({
  routes: [{
      name: 'home',
      path: '/',
      ponent: {
        template: '<div>Home</div>'
      }
    },
    {
      name: 'foo',
      path: '/foo',
      ponent: {
        template: '<div>Foo<router-view></router-view></div>'
      },
      children: [{
        name: 'foo.baz',
        path: '/baz',
        ponent: {
          template: '<div>Baz</div>'
        }
      }, {
        name: 'foo.tar',
        path: '/tar',
        ponent: {
          template: '<div>Tar</div>'
        }
      }]
    },
    {
      name: 'bar',
      path: '/bar',
      ponent: {
        template: '<div>Bar<router-view></router-view></div>'
      },
      children: [{
        name: 'bar.zim',
        path: '/zim',
        ponent: {
          template: '<div>Zim</div>'
        }
      }, {
        name: 'bar.zug',
        path: '/zug',
        ponent: {
          template: '<div>Zug</div>'
        }
      }]
    }
  ]
})

new Vue({
  el: '#app',
  router,
  data() {
    return {
      children: []
    }
  },
  watch: {
    $route: function(current) {
      const route = this.$router.options.routes.find(route => route.path === current.path)

      if (route && Array.isArray(route.children)) {
        this.children = route.children
      } else if (route) {
        this.children = []
      }
    }

I made some modifications to DigitalDrifter's answer where I find the children using the template syntax. I'm pretty sure my answer will stop working after another level of children so I'm going to say DigitalDrifter still has a better answer.

Also I'm not sure how preserve the sub menues route (localhost/Traveller) so it isn't searching the children of (locathost/Traveller/View) when I click on something like view. Right now I'm doing it in kind of a janky way:

v-for="(route, index) in $router.options.routes.filter(x=>x.path==$route.path||$route.path.includes(x.path))"

Thet full SFC without styling is here:

<template>
  <nav id="sidebar">
    <div class="sidebar-header">
      <h3>Bootstrap Sidebar</h3>
    </div>

    <ul class="list-unstyled ponents" v-for="(route, index) in $router.options.routes.filter(x=>x.path==$route.path||$route.path.includes(x.path))">
      <li v-for="child in route.children">
        <a class="nav-item" :key="index">
          <router-link :to="{path: route.path+'/'+child.path}" exact-active-class="active">
            <icon :icon="route.icon" class="mr-2" /><span>{{ child.path }}</span>
          </router-link>
        </a>
      </li>
    </ul>

  </nav>

</template>

<script>
  export default {
    data() {
      return {
      }
    },
    methods: {
    }
  }
</script>

Edit: I know vue has the data I want associated with the routers views as shown here,

I'm just not sure how to access those properties.

Update 1/29/2019:

I figured out that all you need to do to get the path is by using $Route.matched[0].path you can learn more here.

Now I have been able to simplify the menu into an SFC like this:

<template>
    <nav id="sidebar">
      <div class="sidebar-header">
        <h3>Bootstrap Sidebar</h3>
      </div>

      <ul class="list-unstyled ponents" v-for="(route, index) in $router.options.routes.filter(x=>x.path==$route.matched[0].path)">
        <li v-for="child in route.children">
          <a class="nav-item"  :key="index">
            <router-link :to="route.path+'/'+child.path" exact-active-class="active">
              <icon :icon="route.icon" class="mr-2" /><span>{{ child.name }}</span>
            </router-link>
          </a>
        </li>
      </ul>

    </nav>
 
</template>

<script>
    export default {
    data() {
        return {
        }
      }
    }
</script>

CSS not included.
