title: How to auto resize an input field vertically and not horizontally like Facebook by pressing typing or pressing Shift and Enter
body: <p>I have found many plugins that allow a textarea to be resized <a href="http://unwrongest.com/projects/elastic/" rel="nofollow">vertically</a>  and other plugins that allow an input field to be resized horizontally but I have not found one that allows an input field to be resized vertically like Facebook does for it's comment system</p>
  
  <p>How do I resize an input field vertically when the text reaches the end of the input so that the text may go to the next line just like Facebook does with it's comment system ? And how to resize the text also when the shift and enter keys are pressed just like on Facebook ?</p>
