Sprint board (swimlanes + WIP)
An agile sprint board: status lanes crossed with a swimlane per assignee, an enforced WIP limit on In progress, and a story-point roll-up in every lane header via board.laneSummary. Drag across a band to reassign the owner; double-click to edit. Collapsible lanes.
A live, editable Svelte 5 data grid example from the SvGrid gallery (Kanban). See the SvGrid documentation for the full API.
What this example shows

More Kanban examples
- Kanban board mode - The same <SvGrid>, same data + columns, rendered as a Kanban board by setting one `board` prop: rows become cards in horizontal lanes bucketed by a `status` field. Built-in drag-and-drop AND keyboard move (Space + arrows) reassign the lane and reorder; double-click / F2 opens a built-in card editor; WIP limits, add-card, and a rich card snippet (assignee avatar + priority chip). Toggle Board / Table to see it is one grid.
- Sales pipeline (deal board) - A CRM deal board: stages as lanes with a live total-value roll-up per stage (board.laneSummary). Rich deal cards; drag to advance a deal, double-click to edit. Moves and edits persist to localStorage via onCardMove / onCardCommit, so a reload restores the board.
- Large board (virtualized) - Thousands of cards per lane kept smooth with board.virtualized - only the cards in view are in the DOM. A slider scales the board from 1k to 50k cards; drag-and-drop and keyboard move still work across the whole window.
- Support triage board - A helpdesk triage board: status lanes crossed with a priority swimlane, a search box front-and-center, and an SLA colour bar on each card driven by ticket age. Drag across a band to re-triage a ticket priority.
- Content calendar - An editorial pipeline: stage lanes crossed with a swimlane per channel. Rich cards carry a cover glyph, author and target date. Drag a piece down the pipeline, or across a band to move it to another channel; double-click to edit.
