Kanban Sample Code 1

UiKanbanSpecifier buildTodoKanban() {
    new UiKanbanSpecifier().ui {                                                                   (1)
        column 'To Do', Style.ALIGN_CENTER, {                                                      (2)
            custom "Custom header html code"
        }, Gantt2Controller.&changeTodoProgression as MethodClosure, [newProgression: 0], {
            custom "Custom html code"                                                              (3)
            todos.forEach { Todo todo ->
                card todo, Gantt2Controller.&showTodo as MethodClosure, todo.id, {                 (4)
                    cardField todo.what_                                                           (5)
                    cardFieldRaw "Custom html code"                                                (6)
                    cardAction ActionIcon.SHOW * IconStyle.SCALE_DOWN, Gantt2Controller.&doSomething as MethodClosure, todo.id   (7)
                }
            }
        }
    }
}

Drop action

@Transactional
def changeTodoProgression(Integer newProgression) {
    Todo todo = Todo.get(params.long('cardId'))                                                    (10)
    todo.progression = newProgression
    render status: 200
}

Write in a service for register contextmenu

@PostConstruct
void init() {
    TaackUiService.registerContextualMenuClosure(Todo, new UiMenuSpecifier().ui { Long id ->    (8)
        menu 'Show Gantt', Gantt2Controller.&showGanttByTodo as MethodClosure, id                 (9)
    })
}

1	Create the kanban specifier
2	Build kanban column with its label, style and an optional header closure (`custom` only), could pass an action and params called on `Drag`+`Drop` into the column
3	Could add custom html code for the column body
4	Build cards in the column, could pass an action and params as `MouseDoubleClic` for the card
5	Build a line with field in the card, note the underscore at the end of the field name
6	Custom HTML code, rendered as is. `cardField` with a `String` is sanitized (only basic formatting and links are kept); use `cardFieldRaw` for HTML built by the application, never for data typed by users
7	Could add an icon with action bind to clic
8	Register contextmenu as `MouseRight` for the card
9	Add a menu item with action bind
10	The dropped card id is transmitted via the `cardId` parameter, along with the column params

To display the Kanban in a block, use kanban or kanbanFilter to associate a filter:

taackUiService.show(new UiBlockSpecifier().ui {
    kanbanFilter buildTodoFilter(), buildTodoKanban()
}, buildMenu())
