title: How to add an icon in front of every VuetifyJS combobox entry?
body: <p>I'm using the <a href="https://vuetifyjs.com/en/components/combobox" rel="noreferrer">combobox component of VuetifyJS</a> and I need to add an icon in front of every entry in the drop down. How to do that?
  Here is a CodePen example of the combobox: <code>https://codepen.io/anon/pen/KBLXYO</code></p>
  
  <p>HTML</p>
  
  <pre><code> &lt;div id="app"&gt;
    &lt;v-app id="inspire"&gt;
      &lt;v-container fluid&gt;
        &lt;v-layout wrap&gt;
          &lt;v-flex xs12&gt;
            &lt;v-combobox
              v-model="select"
              :items="items"
              label="Select a favorite activity or create a new one"
            &gt;&lt;/v-combobox&gt;
          &lt;/v-flex&gt;
        &lt;/v-layout&gt;
      &lt;/v-container&gt;
    &lt;/v-app&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>JS:</p>
  
  <pre><code> new Vue({
    el: '#app',
    data () {
      return {
        select: 'Programming',
        items: [
          'Programming',
          'Design',
          'Vue',
          'Vuetify'
        ]
      }
    }
  })
  </code></pre>
