How save a text other than the one shown in the form in the recipient's profile

How can you save a value other than the one shown in the form in the personal data field?

In the "Options to show" field, write the pair Choice || Value where:

• Choice is the text displayed within the form;
• Value is the replacement data to be saved in the personal data field and which will constitute the recipient's profile.

For example, if you write Italian || IT:

• Italian will be displayed in the form as a choice option for the user;
• IT will be the text saved in the recipient's personal data field, instead of "Italian".

To create a list of items, it will be necessary to write the different tiles one after the other by wrapping, for example:

Italian || IT

France || FR

Spain || ES
