Indicates the element is participating in form validation. When the <form> is invalid—when any of its fields is invalid—the disabled property of the element will be set to true; false otherwise. It is implied that only elements supporting disabled property can be used for this feature. Typically they are <input type="submit">, <button type="submit">.

Selector Rule:

form .foundation-validation-bind,


  <label>Field 1 <input name="field1" required></label>
  <label>Field 2 <input name="field2" required></label>
  <button class="foundation-validation-bind" type="submit">Submit</button>

In this case, the submit button will be enabled/disabled when the form is valid/invalid.
