How to import (multiple) checkbox custom field values using the built-in 'importer'?
I've read the documentation about '
Customize the AppThemes Importer' but how do I import multiple checkbox values of a custom field using the built-in 'CSV importer'?
For example; I have a custom field labeled 'Number of objects' where '1' till '10' can be checked.
I've tried to do it like the way 'ad_tag' or 'attachments' can be imported by setting a comma seperated value between double quotes, but that doesn't work. (it imports the whole comma seperated string as one custom field value)
