Measured entry

reui-kanban

formminimal-flat

A client-side, controlled Kanban primitive shipped as shadcn registry source rather than a ready-made board. It provides sortable columns, items, drag handles, overlays, keyboard input, and move or commit callbacks. It depends on the dnd-kit packages, Radix Slot, React, Tailwind utility classes, and the local cn helper.

Verdict

A capable controlled primitive, but not a drop-in demo component: the harness mounted the root without its required value contract and it crashed while reading columns. Use it when you will compose the full board and own its state. It needs a shadcn-style setup before it can build or mount in a bare project.

Use it if

  • You need a controlled Kanban board whose data remains owned by your application.
  • You want sortable columns and cross-column item moves with mouse, touch, and keyboard input.
  • You need composable primitives so your own cards, headers, and drag overlays control the presentation.

Skip it if

  • You want a complete board that renders useful content with no props or composition.
  • You do not want to add dnd-kit and Radix dependencies for drag-and-drop behavior.
  • Your data model cannot guarantee unique item identifiers across every column.
  • You need a server-only component without a client-side drag layer.

In a non-shadcn project, install the dnd-kit core, sortable, and utilities packages plus Radix UI. Add React client-component support, Tailwind utilities, a cn class-merging helper, and an alias or revised import for the local utils module. Then supply controlled column data, a change handler, an item identifier function, and composed board children.
