title: How make Vue Multiselect accessible to screen reader?
body: <p>I recently replaced a dropdown with Vue Multiselect.
  I intend to make the multiselect options accessible.</p>
  
  <p>The issue:
  When I press tab the focus does come on the multiselect and read out the default option.
  But, when I press the down arrow key to scroll through the options, the screen reader fails to read them out.</p>
  
  <p>I have tried invoking a fuction to programatically set focus on the child options but that didn't quite seem to completely work,</p>
  
  <p>The following sets focus on the default, but I don't know how to set focus on the child options,</p>
  
  <pre><code>this.$refs.managermultiselect.$el.focus()
  </code></pre>
  
  <p>Following is the HTML,</p>
  
  <pre><code>&lt;multiselect v-model="value"
      aria-autocomplete="list"
      aria-activedescendant=""
      ref="managermultiselect"
      label="LastName"
      @keydown.native="keymonitor"
      :options="manageroptions"
      :multiple="true"
      :custom-label="customLabel"&gt;
  &lt;/multiselect&gt;
  </code></pre>
