Drag & Reorder

Pull to Refresh

A 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.

When to use it

Mobile-style refresh affordance demos, gesture UI previews, or loading-state illustrations on dark dashboards.

When not to

Contexts requiring real data refresh — the spinner is cosmetic only. Light backgrounds clash with the hardcoded dark theme.

Working with an AI agent

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

Change the release threshold to 80px by setting THRESH=80, swap the accent color to purple by changing CY='#a855f7', and increase row count to 7 by setting N=7 and extending rowLab. 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

  • release threshold (THRESH=58)
  • max pull distance (MAXP=92)
  • row count (N=5) and rowLab array
  • accent/spinner color (CY variable)
  • spring stiffness and damping (k=180, c=22)
  • refresh hold duration (refreshT>1.5)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion static-frame guard
  • visibilitychange pause/resume
  • pointer capture (setPointerCapture) for reliable drag tracking
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
  • demo-v1 preview lifecycle: initialize demoEnabled from window.__foreverPreview and stop attract work on the window forever:interactive event; retain manual feedback, settling, cleanup and explicit sessions

Known limitations

  • Light re-theme via the [data-theme=light] token block; catalog bg/accent describe the dark default
  • Refresh action is cosmetic; no network hook or event emitted
  • Row stagger lag (r*0.05 multiplier) becomes visually loose at N>8
  • State remains local to each mounted instance; format/theme remount preserves takeover, not component values.
