// You can also pass an object to override a few options.
$('demo').coolinput({
  useHtml5:true, // Use HTML5's native placeholders when possible.
  hint:null, // Input hint text.
  source:"title", // Source attribute for input hint text. Overrides "hint".
  removeSource:true, // Remove the source attribute after reading its value.
  blurClass:"blur", // Add a class to the input when it loses focus.
  extraClass:false, // Extra classes to ad to the input.
  clearOnSubmit:true, // Clear the input hint when the form is submitted (so an empty value is submitteed).
  clearOnFocus:true, // Clear the input hint when the input is focused.
  persistent:true // If set to false, the input hint will only be visible the first time an input is seen.
});
