🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Generate the Webcal URL from an absolute URL.
When fetchMode is local, Line 204 returns ics/.... Line 205 does not convert that relative value. The rendered Webcal link then resolves as an ordinary document-relative HTTP(S) link instead of a webcal:// subscription URL. This affects the normal path where local ics/index.json loads successfully.
Proposed fix
_getWebcalUrl(entity, category) {
- return this
- ._getCalendarUrl(entity, category, 'ics')
+ return (this.remoteBaseUrl +
+ this._getRelativePath(entity, category, 'ics'))
.replace(/^https?:\/\//, 'webcal://');

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Proposed change
Adds multi-select support to the Download Holiday Calendars page, closing #3733.
Previously, the downloads page only supported selecting one country/region at a time. This PR reworks the page so users can:
For ICS and JSON, downloads are scoped to the selected Year Range: the full static index file (covering 2015-2035) is fetched, filtered client-side to the chosen years, and served as a generated download named e.g.
India-public-2025-2026.ics. Webcal links are intentionally left unscoped by year and continue to point at the full static file, since a live calendar subscription needs a stable URL to keep re-fetching from — a year-filtered result only exists transiently in the browser and can't be subscribed to.Also fixed along the way:
@click.outsidewas bound to the trigger button instead of the wrapping container.x-ifon a plain<span>instead of a<template>, so it silently had no effect and always rendered.white-space: nowraprule left over from the old single-select design, plus amin-widthon the table itself.Type of change
