title: Autocomplete middle of the text not only on start
body: <p>Is there a way to implement a custom autocomplete list in middle of the text not just from the beginning?</p>
  
  <p>Lets say, I have a custom autocomplete list like this.</p>
  
  <pre><code>['@Martin','@Josu','@Mikenko','@Buarandun','@Ravindran','Basix','#ItemNr']
  </code></pre>
  
  <p>When I type the following in the input, <code>'Hallo @M'</code>, it should list <code>['@Martin' ,'@Mikenko']</code></p>
