Vue multiselect with axios call to database, laravel

Question

For some reason, I can't quite figure out how to get an 'autocomplete' style multiselect with Vue working properly.

I properly set the route that is being called in my axios block, and the controller is set to use the query as a way to hit the database with a LIKE clause, but something is going wrong somewhere and my multiselect is not being filled with results from database that would make it searchable.

What am I doing wrong here?

Route:

Route::get('search', 'Controller@searchTags')
    ->name('search');

Controller:

public function searchTags(Request $request)
{
    if ($request->get('query')) {
        $query = $request->get('query');
        $data = TAGS::where('TAG_DATA', 'LIKE', "%{$query}%")->get();

        $output = '<ul class="dropdown-menu" style="display:block; position:relative">';
        foreach ($data as $row) {
            $output .= '<li><a href="#">' . $row->tag_data . '</a></li>';
        }
        $output .= '</ul>';

        return $output;
    }
}

Blade:

<div id="tagContent">
    <multiselect v-model="value" open-direction="bottom" :options="options" :multiple="true" :close-on-select="false" :taggable="true" :clear-on-select="false" :preserve-search="true" placeholder="Add Tag(s)" label="name" track-by="name">
        <template slot="selection" slot-scope="{ values, search, isOpen }"><span class="multiselect__single" v-if="values.length &amp;&amp; !isOpen">{{ values.length }} options selected</span></template>
    </multiselect>
</div>

new Vue({
        components: {
            Multiselect: window.VueMultiselect.default
        },
        data () {
            return {
                value: [],
                options: []
            }
        },
        methods: {
            read(){
                window.axios.get('campaigns/search').then(({ data }) =>{
                    console.log(data)
                });
            },
            addTag (newTag) {
              const tag = {
                name: newTag,
                code: newTag.substring(0, 2) + Math.floor((Math.random() * 10000000))
              }
              this.options.push(tag)
              this.value.push(tag)
            }
        }
    }).$mount('#tagContent');

There are a few things missing from your example, I believe.

1. You need to trigger the read function when the search input changes - use the @search-change event for that

2. You need to make use of the results of your axios request by sending them to this.options , so that the multiselect component can make use of them.

In this example , I've mocked the data request using a timeout, but you should get the idea. You can also make use of the loading property to let your users know something is happening behind the scenes.
