How this works

Each workspace row pairs a rounded-square gradient logo (initials inside) with a two-line label and a small plan .badge pill. The active workspace carries an accent ring on its logo via box-shadow so it reads without needing a check.

A sticky footer action sits outside the scrolling option list using position: sticky; bottom:0, so 'Create workspace' stays reachable in long team lists. The shared listbox handler drives selection while the footer button is a separate focusable control.

Make it yours

  • Give each team a brand color through the data-hue attribute consumed by hsl() in the logo background.
  • Change the active ring thickness/color with --ring.
  • Cap the list height with --list-max before the sticky footer.

Gotchas — read before shipping

  • Sticky footers inside scroll containers need the container to actually scroll; ensure max-height is set or the sticky has no effect.
  • When switching workspaces you typically reload scoped data — debounce rapid switches to avoid race conditions in the app layer.

position:sticky and hsl() are broadly supported; no experimental features.
