<div>
<select data-placeholder="Choose a Country..." class="chosen-select" multiple style="width:350px;" tabindex="4">
            <option value=""></option>
            <option value="Any">[Any]</option>
            <option value="United States">United States</option>
            <option value="United Kingdom">United Kingdom</option>
            <option value="Afghanistan">Afghanistan</option>
            <option value="Aland Islands">Aland Islands</option>
            <option value="Albania">Albania</option>
            <option value="Algeria">Algeria</option>
            <option value="American Samoa">American Samoa</option>

          </select>    
</div>

Solution

li.result-selected { display:none !important; }

Other stuff I tried did not work, but the CSS change works fine:

$('.chosen-select').chosen({}).change(function(obj, result) {
  console.log("selected: " + result.selected);

  /* None of this works. The CSS does work
      const vals = $(".chosen-select").val();
        $('.chosen-select').find("option[value='"+result.selected+"']").remove()
        console.log(vals)
        $(".chosen-select").val(vals);      
            //  $('.chosen-select').trigger("chosen:updated");
  */
});

li.result-selected {
  display: none !important;
}
