Is it possible to show groups (columns) without any items in Kanban view of Odoo10?
I found an article how to do that in Odoo8, but the way that is described there doesn't seem to work anymore:

It looks like if you use Selection field for the group, it doesn't work, but if Many2one is used, then it is showing the empty columns.
