Vue Multiselect doesn't load data

Issue: Vue Multiselect isn't populating with data

Basic Explaination: I am using Vue Multiselect for a dropdown for plans on an application. I am able to get the data to load into the data prop - tested with adding a <p>{{plans}}</p> right below the multiselect in the UI and it outputs the correct data which is an array of objects that should be read by multiselect.

Template code:

<multiselect v-model="plan" deselect-label="Can't remove this value" track-by="id" label="name" placeholder="Select a plan" :options="plans" :searchable="false" :allow-empty="false" :hide-selected="true"></multiselect>

Script code - stripped down:

import axios from 'axios';
export default {
  data() {
    return {
      plan: null,
      plans: null
    }
  },
  created() {
    axios.get('/billing/plansLoad', {})
    .then(plans => {
        this.plans = plans.data.plans
    })
  }
}

For the created section I have tried created, beforeCreate, and beforeMount, all of which don't seem to work.

Extra notes: I can get the multiselect to output the correct data by pasting in the data to the data prop that is returned by the API call.

Whenever there is an initialization race condition where the component needs data on first render, you can use v-if to delay that render until the data is ready:

<multiselect v-if="plans"...

This way the <multiselect> doesn't render at all until the data is already available.
