Vue multiselect not allowing new tags to be created

I have a mostly working Vue multiselect where I"m using an autocomplete function through an axios call to a database. As far as returning the DB results and adding them as options, then tags, it works perfectly.

My problem is that I can't create new tags. So if my axios call returns "Testing one" as an option and I select it, it become a tag. However, if no results are returned when I typ "new test" and hit enter, it doesn't become a new tag.

WHat am I doing wrong?

<div id="tagApp">
<multiselect
  label="tag_data"
  track-by="campaign_tag_id"
  v-model="value"
  :options="options"
  :loading="loading"
  :multiple="true"
  :taggable="true"
  @search-change="val => read(val)"
></multiselect>
</div>

new Vue({
components: {
  Multiselect: window.VueMultiselect.default
},
el: "#tagApp",
data() {
  return{
      value: [],
      loading: false,
      options: []
  }

},
methods: {
  read: function(val){
      //console.log('searched for', val);
    if (val) {
      this.loading = true;
      this.options = [];

      const self = this;
      console.log(val);

      axios.get('campaigns/search',{params: {query: val}})
          .then(function (response) {
              self.options = response.data;
              console.log(response.data);
      });

    } else {
      this.options = [];
    }
  }
}
})

I suggest you read their documentation... Everything you need is there.. you have to add taggable as well as handle the creations with @tag="handleTagMethod"

CodePen mirror: https://codepen.io/oze4/pen/ROVqZK?editors=1010

Vue.component("multiselect", window.VueMultiselect.default);

new Vue({
  el: "#app",
  data: {
    value: [],
    options: []
  },
  methods: {
    addTag(newTag) {
      const tag = {
        title: newTag,
        // you'll need to add other items specific to your objects        
      };
      this.options.push(tag);
      this.value.push(tag);
    }
  },
  mounted() {
    var self = this;
    axios
      .get("https://jsonplaceholder.typicode.com/todos?_start=1&_end=10")
      .then(response => {
        self.options = response.data;
      })
      .catch(error => {
        alert(error);
      });
  }
});
