I know, that joomla 3.x uses bootstrap, both css and js. When I am filling in the registration form and my password is too short for example, I start getting those javascript tooltip error messages. I have added an ajax call to the registration where I check the availability of the username and email. I am getting my string message back succesfully with jQuery ajax. But How can I add that message to my username input field to be shown at the other tooltips?
Thank you!
