    cards: [

function handleMove(event) {
  const newColumns = columns.map((col) => ({
    ...col,
    cards: col.cards.filter((c) => c.id !== event.card.id),
  }));
  const target = newColumns.find((c) => c.id === event.toColumnId);
  target.cards.splice(event.toIndex, 0, event.card);
  columns = newColumns;
}

<KanbanBoard {columns} onmove={handleMove} />

Add-card footer & custom header

onadd is separate from the optional header snippet - this demo uses both for illustration.

Props

Prop	Type	Default	Description
columns required	KanbanColumn[]	-	Array of columns with their cards.
onmove	(event: KanbanMoveEvent) => void	-	Called after a reorder or cross-column drop. Omit only for read-only previews.
onadd	(columnId: string) => void	-	When set, each column shows an “Add card” footer that passes its column id.
columnHeader	Snippet<[KanbanColumn]>	-	Replace the default header row (dot, title, count).
class	string	-	Additional CSS classes on the horizontal scroller.
card	Snippet<[KanbanCard, columnId: string]>	-	Custom card body; you still get drag handles via the outer `dndItem` wrapper.

KanbanColumn

Prop	Type	Default	Description
id required	string	-	Unique column identifier.
title required	string	-	Column header text.
cards required	KanbanCard[]	-	Cards in this column.
color	string	-	Accent color for the column header.

KanbanCard

Prop	Type	Default	Description
id required	string	-	Unique card identifier.
title required	string	-	Card title text.
description	string	-	Optional card description.
labels	{ text: string; color: string }[]	-	Optional label tags with text and color.

KanbanMoveEvent

Prop	Type	Default	Description
card required	KanbanCard	-	The card being moved.
fromColumnId required	string	-	Source column ID.
fromIndex required	number	-	Original index in source column.
toColumnId required	string	-	Target column ID.
toIndex required	number	-	Target index in destination column.

Usage tips

The onmove handler receives the full move event - you’re responsible for updating column state immutably.
Use the card snippet prop for custom card rendering (e.g. avatars, due dates, priority indicators).
Column color is rendered as a header accent - use brand or status colors to differentiate lanes.
Cards support labels for lightweight categorization displayed as tags.
DndGhost and DndIndicator ship inside the component - import bundled styles so drag visuals match other DnD surfaces.
