title: JSF: Prefilled values with input text field?
body: <p>I tried searching, but haven't found the answer.  I see when you ask a question on stackoverflow, the input field for "tags" show the gray text "at least one tag such as...etc".  Upon click, the gray text disappears and you can start typing your values.  If I click off that, the instructions reappear.  How do I do that?  Are there out of box implementations of this functionality or does this require custom implementation?</p>
  
  <p>Thanks!</p>
