Issue of Z-Index of Popup Menu on FullCalendar

PHPMaker 2026.1.

  1. Go to Calendar menu, you will see “+2 more”, just click on that:

  2. You will see a small popup window as follows:

  3. Now just right-click on “12a Test” item, you will get the issue as displayed on the following screenshot, as you can see… the position of popup menu after right-click is under the small windows that displayed before:

That is because FullCalendar sets it popup’s z-index as 9999. You can add the follows in HTML → Styles → User tab:

.ew-calendar-dropdown {
  z-index: 10000;
}

The latest template today has already fixed the issue of popup menu doesn’t show up. Now the popup menu works as expected again. Thanks!
