I'm using validator.js from boottrap to create a register page.
my register page is very close of the exemple of the page : validator.js
In the server side, I'm using spring mvc. I would like to display an error when an email already exist.
In this case I would like that the input-group is marked as error with the error message.
Exactly the same as validator.js do when the email address is not well formatted.
This is the actual thymeleaf code to display the email input
