title: Yii CGridView hide filter input only
body: <p>When using CGridView, the filter input fields are automatically generated by the component.</p>
  
  <p>I want to select which columns will show the input field. For example:
  My model has 5 columns. I want CGridView to show the input filter ONLY for columns 1 and 2.</p>
  
  <p>Is there a way to do it without using CSS or jQuery, just adding some code on the CGridView options?</p>
