Custom Language field

This module creates a Language Field in D7 and D8. It provides a Field Formatter with several options. Flag icons can be used using either the Language Icons module or the Flags module

Use this module if you need more languages then the enabled languages, but do not need the translations. Example: Your site contains two configured languages, but contains content type 'Manuals' in 5 languages.

In D7, you add and then disable a new language.
In D8, this core feature is lost. So, you can create 'custom languages', instead.
Per field instance you can decide to display all, all enabled or all installed languages.

D8 core also has a standard language widget and formatter for the core language property. Differences between both are:

• standard language formatter: show (translated) Name;
• custom language formatter: show combination of Language icon, ISO 639-code, (translated) Name, Native name;
• standard language widget: only a select list of configured languages;
• custom language widget: select list or autocomplete with wide possibility of languages;

A Feeds import mapper is provided for Drupal 7.
