title: React Tabulator select in headerFilter
body: <p>I am having an issue with react-tabulator 4.8.  I have the following field defintion:</p>
  <pre><code>{ field: 'location', title: 'Location', headerFilter: 'select', headerfilterParams: { 'here':'Here', 'there':'There' } }
  </code></pre>
  <p>Rather than getting a true HTML <code>&lt;select /&gt;</code> element I get a <code>&lt;input type=&quot;search&quot; /&gt;</code> element.  It appears to work <em>mostly</em> the same, but it lacks the down-caret on the right as a visual indicator that it is, in fact, a select and not a free-text input.  Is there some trick to forcing the use of the <code>&lt;select /&gt;</code> element?</p>
