When to use it

Showcasing drag-to-reorder UI patterns, kanban onboarding demos, or project-management feature previews.

When not to

Production task management — auto-demo loop and fixed card set must be removed and replaced with real data before shipping.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Change the demo interval from 2200ms to 1400ms, add a fourth column, and swap the accent color from cyan (#22d3ee) to violet (#a855f7). Theme: dark tokens live in :root, the light variant in :root[data-theme="light"]; ?theme=light or a {type:'forever:theme'} postMessage switches at runtime.

Safe to edit

  • demo interval (2200ms in setInterval)
  • column count (COLS=3)
  • accent color (--dr02-acc)
  • spring stiffness (0.18) and damping (0.34)
  • initial card layout (layout array)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • FLIP engine (flipReorder + measure functions)
  • IIFE wrapper
  • prefers-reduced-motion static fallback
  • visibilitychange pause
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Auto-demo loop must be disabled for real user-controlled boards
  • Card content is decorative CSS pseudo-elements only — no real text
  • Pointer drag uses column-width snapping, not pixel-precise drag

More Drag & Reorder components

  • FLIP Reorder7-row list reorders via FLIP spring physics on drag or arrow-key input; lifted card gains glow outline while others spring to new slots. Auto-demos when idle.
  • Pull to RefreshA 5-row canvas list springs down on drag, revealing diagonal bars and a rotating geometric indicator; releasing past threshold triggers a 1.5s sync spinner.
  • Sortable Grid3x3 grid of colored numbered tiles that spring-animate into position as tiles are dragged or swapped; auto-shuffles on idle as a demo.
  • Snap SliderOchre-accent range slider with 9 tick detents; thumb flicks with spring momentum and rubber-bands at ends. Self-demos on idle, accepts keyboard input.
  • Dual RangeCanvas dual-range slider with two spring-driven thumbs (white lo, amber hi), hatched fill, delta readout, and tick marks. Auto-breathes when idle.
  • Carousel ThrowSeven colored cards orbit a glowing hub in a radial ring; drag to fling with angular inertia, release to snap to the nearest card under the marker.
