Bulma's navbar-buger doesnt connect to menu items in Vue.js 2

Question

I am trying to implement a navbar for my application whose front end is built using Vue 2.0 and Bulma . It works well on desktops and but on smaller screens its showing the burger icon but it is not showing any elements. Its just present.

<template>
<div class="container is-fluid">
    <div>
      <nav class="navbar is-dark">
        <div class="navbar-brand">
          <a class="navbar-item" href="#">
              <img  alt="K R O N O S" height="100px">
          </a>
          <div class="button navbar-burger" data-target="navMenu">
              <span></span>
              <span></span>
              <span></span>
        </div>
        </div>
        <div class="navbar-menu" id="navMenu">
          <div class="navbar-end">
            <div class="navbar-item">
              <a class="" href="#"> Docs </a>
            </div>
            <div class="navbar-item ">
              <a class="" href="#"> Report </a>
            </div>
            <div class="navbar-item">
              <a class="">More</a>
            </div>
            <div class="navbar-item">
              <a class="">Logout</a>
            </div>
        </div>
      </div>
    </nav>
  </div>
</div>
</template>

<script>

document.addEventListener('DOMContentLoaded', function () {
  // Get all "navbar-burger" elements
  var $navbarBurgers = Array.prototype.slice.call(document.querySelectorAll('.navbar-burger'), 0)
  // Check if there are any navbar burgers
  if ($navbarBurgers.length > 0) {
    // Add a click event on each of them
    $navbarBurgers.forEach(function ($el) {
      $el.addEventListener('click', function () {
        // Get the target from the "data-target" attribute
        var target = $el.dataset.target
        var $target = document.getElementById(target)

        // Toggle the class on both the "navbar-burger" and the "navbar-menu"
        $el.classList.toggle('is-active')
        $target.classList.toggle('is-active')
      })
    })
  }
})
export default {
  name: 'Navbar',
  data () {
    return {
      msg: ''
    }
  }
}
</script>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
div{
  border: 0px solid black;
}
</style>

As you can see I have tried implementing the example code in on which was present here but with no use. Shouldnt Bulma give me responsive navbar out of the box. All the examples and solutions I have found are for the older "nav" class not the newer "navbar". Help would be much appreciated.

So, after a bit of studying the Vue guide and clues from fatman's comments, this is the fix I applied.

The above code works , but this is a more vue-ish way to do the navbar-burger menu.

<template>

      <nav class="navbar">
        <div class="container">
        <div class="navbar-brand is-large">
          <a class="navbar-item" href="#">
              <img  alt="K R O N O S" height="100px">
          </a>
          <button @click="makeBurger" class="button navbar-burger" data-target="navMenu" v-bind:class="{ 'is-active': activator }">
              <span></span>
              <span></span>
              <span></span>
        </button>
        </div>
        <div class="navbar-menu" id="navMenu" v-bind:class="{ 'is-active': activator }">
          <div class="navbar-end">
            <div class="navbar-item">
              <a class="" href="#"> Docs </a>
            </div>
            <div class="navbar-item ">
              <a class="" href="#"> Report </a>
            </div>
            <div class="navbar-item">
              <a class="">More</a>
            </div>
            <div class="navbar-item">
              <a class="">Logout</a>
            </div>
        </div>
      </div>
      </div>
    </nav>

</template>

<script>
export default {
  name: 'Navbar',
  data () {
    return {
      msg: '',
      activator: false
    }
  },
  methods: {
    makeBurger () {
      this.activator = !this.activator
      return this.activator
    }
  }
}
</script>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
div{
  border: 0px solid black;
}
</style>

Hope this helps someone. The show/hide functionality is taken care by Bulma.

Answer 2

This works, but

1. will not close the menu
2. will cause router-links not to work

For 1.) I recommend adding @click to navbar-item as well:

<a @click="makeBurger" class="navbar-item">
    <router-link to="/login">
        {{link1}}
    </router-link>
</a>
