Unknown custom element: <multiselect> when using vueMultiSelect

This is with these versions:

  "dependencies": {
    "vue": "^2.1.6",
    "vue-form-generator": "^2.0.0-beta1",
    "vue-multiselect": "next"
  },

When I try to use a vueMultiSelect field, I get this error in the console:

[Vue warn]: Unknown custom element: <multiselect> - did you register the component correctly? For recursive components, make sure to provide the "name" option. 
(found in component <field-vueMultiSelect>)

Here’s all the relevant code:

main.js

import Vue from 'vue'
import VueFormGenerator from 'vue-form-generator'
Vue.use(VueFormGenerator)

window.VueFormGenerator = VueFormGenerator

import MyComponent from './components/MyComponent.vue'

MyComponent.vue

<template lang='html'>
  <div id='my-component'>
    <form>
      <vue-form-generator :schema='schema' :model='model' :options='formOptions'></vue-form-generator>
    </form>
  </div>
</template>

<script>
import Multiselect from 'vue-multiselect'
window.VueMultiselect = Multiselect

export default {
  name: 'my-component',
  components: { Multiselect },
  data () {
    return {
      model: {
        skills: ['Javascript', 'VueJS'],
      },
      schema: {
        fields: [
          {
            type: 'vueMultiSelect',
            multiSelect: true,
            label: 'Skills',
            model: 'skills',
            values: ['Javascript', 'VueJS', 'CSS3', 'HTML5']
          }
        ]
      }
    }
  }
}
</script>

I was initially getting this error as well:

'vue-multiselect' is missing. Please download from https://github.com/monterail/vue-multiselect and load the script in the HTML head section!

which comes from here.

I added the import and window. at the top of MyComponent to fix this, by trying to do what fieldVueMultiSelect.vue is expecting. That got rid of that error, but I still get the Unknown custom element: <multiselect> error.

Register the component globally. Add this to your main.js before new Vue()

import Multiselect from 'vue-multiselect';
Vue.component('multiselect', Multiselect);

And ofc don’t forget to import CSS style for Multiselect. Example here

This error is still thrown. Is there any way to make it work?
