var example2 = new Vue({
  el: '#example-2',
  data: function() {
    return {
      openedMenuPositionIds: [],
    }
  },
  // define methods under the `methods` object
  methods: {
  
    addToOpenedMenuPosition(id) {

      // Get the index of id in the array
      const index = this.openedMenuPositionIds.indexOf(id);
      if (index > -1) {
        // This means id is present in the array, so remove it
        this.openedMenuPositionIds.splice(index, 1);
      } else {
        // This means id is not present in the array, so add it
        this.openedMenuPositionIds.push(id);
      }
      
      // You can use this to debug purpose
      console.log( this.openedMenuPositionIds )
    }
  }
