We've enhanced our custom validation feature for Pages by adding the ability to display custom error messages when validation fails.

This improvement gives you more control over the user experience of your forms, allowing you to provide clear, specific guidance when their input doesn't match your requirements.

Example use cases:

• Show "cannot have whitespace" for fields requiring no spaces

• Display "must include your company email domain" for email validation

• Provide "password must contain at least one special character" for password fields

Custom error messages work with all field types that support custom validation, including short text, long text, email, URL, date, and number fields.
