How do I add "Search mode..." option to any many2one field? By selecting this option tree view opens up where I select one record.
I found similar example in Messaging model: 1. I select "Join a group" in "My Groups" category, 2. click "Create", 3. click the expand option for "Authorized Group" many2one list 4. There are listed "Create and Edit" and "Search More..." options. When I click "Search More" it opens up a search tree.
Please, how do I implement the same thing?
