    I have added a custom field of type Classification to Documents & Files.

    The Download list widget has options to filter ("narrow selection") by Categories, Tag, and/or Dates.  Is there a way I can add my custom classification field as one of the options?

    If not, is there a way I can filter the list by a one of the custom classification field values?  I thought this might be possible using the FilterExpression value, but I was not sure how to build the expression.
    (from Download list Edit screen, Advanced -> ControlDefinition -> Views -> FilterExpression)

    Hello Antoine,

    You are on the right track - you can achieve the desired functionality by adding the following to the FilterExpression:

    AND TestFilter.Contains((fc16ede5c205-4ab0-b9da-9ba4060d8ea9))

    where TestFilter is the name of the custom field ( your custom classification type ) and the guid is the id of the custom classification, which can be found in the database.

    Object reference not set to an instance of an object.

    This is the message that I receive when I try to do this. I have tried everything. The only thing that would successfully filter was AND 1 = 0 which hides all records.
