RelatedItemsFieldWidget exclude Items with Interfaces (IWorkingCopy)

Is it possible to exclude all items with a specific Interface?

In our case, we have to not list all Working-Copies in RelatedItems Field - hide all items which have an "IWorkingCopy" Interface...

The other way is possible, i know ... :slight_smile:

    'object_provides': IWorkingCopy.__identifier__

Thank you

You could set a different vocabulary for the field, one that doesn't include IWorkingCopy items.

I imagine you could do this by using a custom behavior which extends IRelatedItems and defines its own relatedItems field.
Use that behavior instead of the IRelatedItems one and you should be good to go.
