Form Validation

Browser Default

Browser default validation with using the required keyword. Try submitting the form below. Depending on your browser and OS, you’ll see a slightly different style of feedback.

Custom Styled Validation

For custom Bootstrap form validation messages, you’ll need to add the novalidate boolean attribute to your <form>. This disables the browser default feedback tooltips, but still provides access to the form validation APIs in JavaScript.

Custom Styled Validation with Tooltips

If your form layout allows it, you can swap the .{valid|invalid}-feedback classes for .{valid|invalid}-tooltip classes to display validation feedback in a styled tooltip. Be sure to have a parent with position: relative on it for tooltip positioning. In the example below, our column classes have this already, but your project may require an alternative setup.
