A Kanban board is a work and workflow visualization used to communicate the status and progress of work items. Click on the color of a note to cycle through colors.

This design and implementation were adapted from the Swim Lanes (vertical) sample. Unlike that sample:

- there are no Links
- lanes cannot be nested into "pools"
- lanes cannot be resized
- the user cannot drop tasks into the diagram's background
- all tasks are ordered within a single column; the user can rearrange the order
- tasks can freely be moved into other lanes
- lanes are not movable or copyable or deletable

### GoJS Features in this sample

#### Table Panels

The "Table" Panel, Panel.Table, arranges objects in rows and columns. Each object in a Table Panel is put into the cell indexed by the value of GraphObject.row and GraphObject.column. The panel will look at the rows and columns for all of the objects in the panel to determine how many rows and columns the table should have. More information can be found in the GoJS Intro.

#### Grid Layouts

This predefined layout is used for placing Nodes in a grid-like arrangement. Nodes can be ordered, spaced apart, and wrapped as needed. This Layout ignores any Links connecting the nodes being laid out. More information can be found in the GoJS Intro.

#### Custom Layouts

GoJS allows for the creation of custom layouts to meet specific needs.

There are also many layouts that are extensions -- not predefined in the `go.js` or `go-debug.js` library, but available as source code in one of the three extension directories, with some documentation and corresponding samples. More information can be found in the GoJS Intro.

#### Groups

The Group class is used to treat a collection of Nodes and Links as if they were a single Node. Those nodes and links are members of the group; together they constitute a subgraph.

A subgraph is not another Diagram, so there is no separate HTML Div element for the subgraph of a group. All of the Parts that are members of a Group belong to the same Diagram as the Group. There can be links between member nodes and nodes outside of the group as well as links between the group itself and other nodes. There can even be links between member nodes and the containing group itself.

More information can be found in the GoJS Intro.

#### Buttons

GoJS defines several Panels for common uses. These include "Button", "TreeExpanderButton", "SubGraphExpanderButton", "PanelExpanderButton", "ContextMenuButton", and "CheckBoxButton". "ContextMenuButton"s are typically used inside of "ContextMenu" Panels; "CheckBoxButton"s are used in the implementation of "CheckBox" Panels.

These predefined panels can be used as if they were Panel-derived classes in calls to GraphObject.make. They are implemented as simple visual trees of GraphObjects in Panels, with pre-set properties and event handlers.

More information can be found in the GoJS Intro.
