title: How to customize the position of an alert box
body: <p>I am using an alert box to alert some messages after some validation.
  Now I want to make alert box position over the control where it had a validation 
  error.</p>
  
  <p>As a default, an alert box pops up in center of page,
  Now I want it at some custom position, 
  for example I have 4 textbox to be validated, textbox-3 has some incorrect data, 
  I want the alert to be presented just above the textbox-3 instead of center of page.</p>
  
  <p>Is this possible to change the display behavior of alert box?
  If there's no other option to go for jquery dialog box.</p>
