Joomla 4/5 User Manual
Adding custom fields/Url Field
Provides a URL text input field.
Special options within this field are:
The allowed schemes are HTTP, HTTPS, FTP, FTPS, MAILTO, URL and FILE. This custom field essentially is a text field with the type of url in the backend while creating an article or a contact or a third party component that supports custom fields. It is only possible to fill in a qualified url - that is one with a scheme and domain such as
http://example.com. The url will be translated into punycode prior to saving. This assures that the url will work as intended regardless of environment.
Use this option to determine whether or not relative URLs are allowed.

Fields are only displayed in the frontend if you have filled them with data in the article. If it is not a required field, can you forget it?
