Columns in React Kanban component

The Kanban columns represent the each stage of the process. The column definitions are used as the dataSource schema in the Kanban. The Kanban operations such as drag-and-drop, swimlane, and toggle columns are performed based on column definitions.

Single-key mapping

Kanban columns are categorized by mapping the key from the datasource using the keyField property. The corresponding value in the datasource is mapped inside the columns keyField. Based on this categorization, Kanban columns are split on this board.

The keyField property is mandatory to render the columns in the Kanban board.

Initially collapsed column

By default, all columns are on expanded state when loading the Kanban board initially. But, you can render the columns with collapsed state using the isExpanded property.

The isExpanded property only works when enabling the allowToggle property on particular column.

In the following example, the backlog column is collapsed on initialization of Kanban board.

Stacked headers

Stacked headers are the additional headers to column header that will group the similar columns.

Define the grouping of columns key value to the keyFields property and provide the custom header text name to grouped columns using the text property, which is placed inside the stackedHeaders property.

In the following code, the kanban columns ‘InProgress, Review’ are grouped under ‘Development Phase’ category.
