Defining a `required` field in Bootstrap

Question

How do I define text field as required (with red border) in Twitter Bootstrap 3?

required=\"required\" doesn\'t work...

Answer 1

Form validation can be enabled in markup via the data-api or via JavaScript. Automatically enable form validation by adding data-toggle="validator" to your form element.

<form role="form" data-toggle="validator">
   ...
</form>

Or activate validation via JavaScript:

$('#myForm').validator()

and you need to use required flag in input field
