title: Yii CGridView - Custom Columns
body: <p>been looking for a solution to add a feature for "Custom Columns"... Meaning, I present a list of columns that I can show the user and he selects the ones he wants to see and after the selection the table is updated and add/removes the needed columns.</p>
  
  <p>Didn't find anything on Google (perhaps it has a different name than what I was looking for...)</p>
  
  <p>Anyone has an Idea on how it can be accomplished?</p>
  
  <p>Thanks in advance!</p>
