Angular UI Bootstrap typeahead-append-to
<p>I'm trying to append the Angular UI Typeahead control to a custom element in my HTML.  The docs state this:</p>

<blockquote>
  <p>typeahead-append-to $ (Default: null) - Should the typeahead popup be appended to an element instead of the parent element?</p>
</blockquote>

<p>I cannot for the life of me figure what to set this value to!  I have tried all combinations of '#elementId' and '.elementClass' but still having no luck.</p>

<p>I can append to the body no probs with typeahead-append-to-body="true", but that's not what I want to do.</p>

<p>Help please! </p>

<p>Cheers</p>
