Allow individual choices (ui-select-choice directive)

[justinwinslow]

I might just be missing something but it doesn't seem like there's a way to just write the available options into the view like a normal select box. If that's the case it would be great if there was a singular choice directive:

<ui-select ng-model="model">
  <ui-select-match placeholder="Some text"></ui-select-match>
  <ui-select-choice ui-select-value="Some Value">
    Some Label
  </ui-select-choice>
  <ui-select-choice ui-select-value="Another Value">
    Another Label
  </ui-select-choice>
</ui-select>
