title: Header filtering - create Select field with down arrow
body: <p>I am using Tabulator 5.x. I have a table with header filtering. The column in question is the last column &quot;Transcribed&quot;. Is there a way to have the typical down arrow on the right side of the select box that shows the end user it is a drop down list similar to if you were using  option in html? Rather than having to click on it filter field to see the choices.</p>
  <p>I looked in documentation but do not see any examples using a down arrow. I also looked in the CSS, but did not anything if indeed it was there.</p>

  <pre><code>var table = new Tabulator(&quot;#transcription-table&quot;, {
  height:&quot;640px&quot;,
  layout:&quot;fitDataStretch&quot;,
  ajaxURL:&quot;get_transcriptions.php&quot;,
  columns:[
      {title:&quot;ID&quot;, field:&quot;id&quot;, headerSort:false, visible:false},       
      {title:&quot;Song Title&quot;, field:&quot;songtitle&quot;, width:350, sorter:&quot;string&quot;, headerFilter:&quot;input&quot;},
      {title:&quot;Artist / Group&quot;, field:&quot;artistgroup&quot;, widthGrow:1.5 ,sorter:&quot;string&quot;, headerFilter:&quot;input&quot;},
  
      {title:&quot;Transcribed&quot;, field:&quot;transcribed&quot;, widthGrow:1.2, sorter:&quot;string&quot;, headerTooltip:&quot;Transcribed into music notation&quot;, editor:&quot;select&quot;, editorParams:{values:{&quot;Yes&quot;:&quot;Yes&quot;, &quot;No&quot;:&quot;No&quot;}}, headerFilter:true, headerFilterParams:{values:{&quot;Yes&quot;:&quot;Yes&quot;, &quot;No&quot;:&quot;No&quot;, &quot;&quot;:&quot;&quot;}}},
      
      ]
  });
  </code></pre>
