The ACF Multilingual plugin lets you choose translation options for your field groups. See which translation preferences field types use in the pre-set translation options and how to use them in Expert mode.
Setting the Translation Preferences in Expert Mode
In the Expert translation option, you need to set the translation preference for each field in the field group by yourself. WPML lets you choose from four translation preferences:
Translate – This option makes your custom field values available for translation. It is recommended for text fields (e.g. Text, Text Area, WYSIWYG, Message).
Copy – This option copies the field value from the default language into the secondary language(s), which keeps your custom field value in sync across all languages. It is recommended for fields like Number, Range, True/False, and similar. Please note that with this option, the value of the field will not be available in WPML’s Advanced Translation Editor.
Copy Once – This option copies the value of the field from the default language, but the value of the field can be changed later in the WordPress native editor. After the first copy, it will not be kept in synchronization with the default language. Please note that when you use this option, the value of the field will not be available in WPML’s Advanced Translation Editor. You need to translate your content manually.
Don’t translate – The field is not available for translation. This is the default setting for fields which you have not yet set a translation preference for. However, if you have any custom fields you don’t want to translate, you should change them to use the Copy option.
Pre-Set Translation Preferences
In the Same fields across languages or Different fields across languages translation options, the translation preferences of your custom fields are pre-set for you.
Below, we show you the translation preference different field types use in these translation options. Here’s a brief explanation of the information you can find below each column header:
Different fields across languages:The pre-set translation preference for each field type for this translation option. You can use different custom fields and/or have a different number of field instances across languages. This is especially useful if you are using Repeater or Flexible Content fields. Please note that you can only translate the custom field content using the native WordPress editor.
It is worth noting that field types set to Copy in Same fields across languages are set to Copy Once in Different fields across languages.
