title: Vuetify concatenate two fields in v-select's item-text
body: <p>Is there a way to concatenate two fields together in a v-select's item-text field?  </p>
  
  <p>I have it working for the drop down list values, but the visible entry doesn't show the two fields.</p>
  
  <p>Problem is here: item-text="'${data.item.name}, ${data.item.group}'"</p>
  
  <p>Code:</p>
  
  <pre><code>`&lt;v-select label="Select" v-bind:items="people" v-model="e11"
    item-text="'${data.item.name}, ${data.item.group}'"
    item-value="name" max-height="auto" autocomplete &gt;
    &lt;template slot="item" slot-scope="data"&gt;
      &lt;v-list-tile-content&gt;
        &lt;v-list-tile-title 
           v-html="`${data.item.name}, ${data.item.group}`"&gt;
        &lt;/v-list-tile-title&gt;
        &lt;v-list-tile-sub-title 
           v-html="data.item.group"&gt;
        &lt;/v-list-tile-sub-title&gt;
      &lt;/v-list-tile-content&gt;
     &lt;/template&gt; 
  &lt;/v-select&gt;`
  </code></pre>
