How do I only show an element if nested ng-repeat is not empty?

I ended up with the following solution which worked perfectly. Plnkr

By setting a variable in the inner ng-repeat I was able to evaluate ng-show based on this variables length like so :

<input ng-model="searchText"/>
<span ng-show='filtered.length > 0'>
  <ul>
    <li ng-repeat="el in filtered = (model | filter:searchText)">
      <div>{{el.label}}</div>
    </li>
  </ul>
</span>
