[solved] filterable file-field in backend?

hi!

i am wondering if it is possible to configure a BE-column to display a custom field of type "file" to just show whether or not there is a file. (I'm talking about BE > FC > Items.)

I'm trying to create an excel-like filter that i can set to 'empty' or 'not empty' instead of seeing all the attachment-names of my items.

I see that in the type-config > "Items Manager Configuration" > "Custom Fields for Items List" the tooltip says something about setting a "display variable" to other than "display". What would that be? And am i looking in the right direction here?

thanks a lot!

Yes you can add the fieldname there and display it e.g. add myfilefield

-- about custom display variable for file field, current there is only the default variable ('display')

so you can use:
myfieldfield
OR
myfieldfield:display

-- about filter of items that or do not have value on custom fields, this is something that is not currently available, but it is possible to implement in future version

ok, thanks for your quick response and great support as always!
