I have an input field which works in such a way that there is a button to add multiple user names so after clicking add user button each time an input field gets added to the list which asks user to input another username so there is a validation for it which works like if user name is not valid according to condition it shows valid username is required but this validation message occurs only for the first input after that for all inputs in the list like second, third and so on it does not occur so what is the possible solution for it.
