                              implicitHeight: Kirigami.Units.gridUnit * 3

  In my case with 11 events marked as allday in my calendar per day this value is a bit too small. But I guess my usecase is maybe not the one everyone has :)

  There are multiple ways to solve this problem:

  • Make the size resizable by the user
  • Use enough place to have all events displayed but it scrolls with the rest of the page

  I would prefers the first solution and if you agree, i could implement it in another MR
