French Form Validation
Custom styles
For custom Bootstrap form validation messages, you’ll need to add the novalidate boolean attribute to your <form>.
Valid Status
You can denote a valid status by applying a helper text with the class .valid-feedback.
Invalid Status
You can denote a invalid status by applying a helper text with the class .invalid-feedback.
Supported elements
Validation styles are available for the following form controls and components.
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.
