Width

By default, the Kanban is adaptable to its parent container. It can adjust its width of columns based on parent container width. You can also assign width of [kanbancolumns] in percentage.

The following code example describes the above behavior.

NOTE

allow-scrolling should be false while defining width in percentage.

Min Width

Min Width is used to maintain minimum width for the Kanban. If the Kanban width is less than min-width then the scrollbar will be displayed to maintain minimum width.
