Language Alternative Support - adobe-dmeservices/custom-metadata GitHub Wiki
For many metadata scenarios, it is common for certain properties to represent text that may have localized values. For text fields, you can optionally enable Language Alternatives to display additional fields to users that align with specific localizations.
Once enabled, you can select one or more locale codes to display as alternative entry fields, although it is not required to have a specific language defined. You can select and deselect locale code in the dropdown to enable and disable alternative language fields. As you select each value, you will see the locale code populate in the Language Alternative field. Note: The list of country codes is prepopulated.
The first locale code you select will be automatically set as the default Language Alternative. You can change this choice if necessary.
When you view a Language Alternative field in a View, you will see the Default value indicated next to the name of the field. In addition, a drop down will appear under the text field.
Expanding the dropdown menu will reveal the Alternate Language fields. You can insert strings of text in these fields for alternative languages.
