 In this article, you will learn how to fold/unfold (selection field) states (not many2one field), in kanban view in Odoo8. The Kanban view is the most attractive and flexible in Odoo. By using this view we can split items into distinct groups (in the form of a row of columns).

Other than many2one fields mean than in this article we are going to fold and unfold states (Selection field, not many2one) based on states.
