The Kanban board UI virtualization feature allows for rendering the column cards that are visible within the viewport, without buffering the entire data source. To enable virtualization, you can set the enableVirtualization property to true. In this demo, a dataset of 100K items has been configured for the dataSource property. Despite the large dataset, the Kanban board efficiently handles the rendering and interaction, ensuring a smooth user experience. Users can seamlessly navigate and interact with the Kanban board, even with such a significant amount of data.
