Hi @balu,
Welcome to the Auth0 Community!
I understand that you would like to add additionalSignUpFields to your sign-up page.
To do so, I recommend reading our How to configure additional signup fields on the Universal Login Page FAQ to learn more.
If you find the FAQ useful and helped you in getting the additionalSignUpFields configured, could you please like our FAQ?
In the meantime, if you have any further questions, please feel free to reach out.
Thank you!
