title: Yii2 gridview filter by using autocomplete textbox
body: <p>Before I have used comboBox instead of default(textBox) for searching in the gridview by using this one:</p>
  
  <pre><code>[
      'attribute' =&gt; 'project_status', 
      'filter' =&gt; $someArray,
      'value' =&gt; 'projectstatus.name',
  ]
  </code></pre>
  
  <p>But I want to change from comboBox to autocomplete textBox so the search function is still working.</p>
