Vue Router: hide parent template when child is open

Question

Im trying to install Vue.js with the router and im running into some view issues. I have a router.js with child routes. I want to use this method for simple breadcrumbs and generate a clear overview so i know which route belongs where.

Opening each route works like a charm, everything shows up. When i open /apps I get a nice view from my Apps.vue that displays App overview</h1>. But now im opening /apps/app-one and then I see the Apps.vue and AppOne.vue template. How can I prevent that both templates are displayed?

The vue components looks like this:

Router.js

import Router from 'vue-router';
import AppsPage from './components/Apps.vue'
import AppOne from './components/AppOne.vue'
import AppTwo from './components/AppTwo.vue'

export default new Router({
    // mode: 'history',
    routes: [
        {
            path: '/apps',
            component: AppsPage,
            children: [
                {
                    path: '/apps/app-one',
                    component: AppOne,
                },
                {
                    path: '/apps/app-two',
                    component: AppTwo,
                },
            ]
        },
    ]
});

Apps.vue

<template>
    <div id="app-overview">
        <h1>App overview</h1>
        <router-view></router-view>
    </div>
</template>

<script>
    export default {
        name: 'app_page'
    }
</script>

App1.vue

<template>
    <div>
        <h1>App 1</h1>
    </div>

</template>

<script>
export default {
    name: 'app_one'
}
</script>

App2.vue

<template>
    <div>
        <h1>App 2</h1>
    </div>

</template>

<script>
export default {
    name: 'app_two'
}
</script>

Having your routes in a parent-child relationship means that the child component will be rendered inside the parent component (at the <router-view>). This is expected behavior.

If you do not want the parent component to be visible when the child route is active, then the routes should be siblings, not nested:

[
    {
        path: '/apps',
        component: AppsPage,
    },
    {
        path: '/apps/app-one',
        component: AppOne,
    },
    {
        path: '/apps/app-two',
        component: AppTwo,
    },
]

The structure of the routes reflects the way they are rendered on the page.
