Live Preview
Widget is hidden — no events matched your filters.
This is because data-hide-if-empty="true" is set.
On a real page the widget takes up zero space.

Preview runs the real widget JS, exactly as it appears embedded on a page. It is held to about one screen, like a real browser window, so scroll inside it to see the rest of a busy month.
