Wondering whether anyone could explain how to create the error validations on the full name and email fields in the URL below:https://marketplace.service.gov.au/2/signup
I had a go using dynamic panels but there seems to be too many borders and interactions on the fields.
You don't need dynamic panel.
Give your text fileds name (Usernametxt, and Passwordtxt)
On click of the login button add conditions and that should work. you can any validation you like.
