How this works

Each option aligns a fixed-width .sym badge, a monospaced .code, and a muted name using CSS grid-template-columns so symbols of different widths ($, €, ¥) stay perfectly column-aligned. The trigger uses a layered conic-gradient border via a ::before mask trick for a premium sheen.

Opening animates a clip-path inset from the top so the panel appears to unfold, combined with an opacity fade — both GPU-friendly. The selected symbol is mirrored into the trigger badge on cs:pick, and all interaction is keyboard-accessible through the shared listbox handler.

Make it yours

  • Adjust the symbol badge size with --sym-size on .cs-02.
  • Retune the gradient border by editing the conic-gradient stops on .cs-02__trigger::before.
  • Change column widths in --cs-cols if you localize to longer ISO labels.
  • Set --glow to shift the accent glow color under the trigger.

Gotchas — read before shipping

  • Monospace alignment depends on a real mono stack; if the host page overrides font-family, codes may drift — the demo pins ui-monospace.
  • clip-path reveal has no fallback below Safari 13.1; those users see an instant open, which is acceptable degradation.
  • Currency symbols vary by locale (e.g. $ is ambiguous); always pair the symbol with the ISO code as shown.

Browser support

clip-path reveal and conic-gradient border need modern engines; older browsers fade only.
