TAG berita multi select mysqli, php dan adminLTE

Assalamualaikum Warahmatullahi Wabarakatuh...
 
berikut saya share untuk tag berita dengan plugin 
https://github.com/brianreavis/selectize.js
 
		$('#chosen-tags').selectize({
		plugins: ['remove_button'],
		persist: true,
		create: true,
		render: {
		item: function(data, escape) {
			return '<div>' + escape(data.text) + '</div>';
					}
				}
			});
	<!-- chosen -->
<link href="url/chosen.css" rel="stylesheet" type="text/css" />
<script src="url/chosen.jquery.js" type="text/javascript"></script>
 
//fungsi PHP
 
function GetTag($key, $Label, $Nilai='') {
global $db;
  $s = "select * from tag order by nama_tag";
  $r = $db->query($s);
  $_arrNilai = explode(',', $Nilai);
  $str = '';
  while ($w = $r->fetch_array()) {
    $_ck = (array_search($w[$key], $_arrNilai) === false)? '' : 'selected';
	$str .= '<option value="'.$w[$key].'" '.$_ck.' >'.$w[$Label].'</option>';
  }
  return $str;
}
