You can modify targetCalendar, divideGap, locale ande timeStyle for your purpose.

To beautify;

/* css/custom.css */
.CX3 .event.calendar_Reservation .headline .time {
  display: none;
}

#CX3_POPOVER .title .count,
.CX3 .calendar_Reservation .title .count {
  font-weight: bold;
  color: gray;
}

#CX3_POPOVER .title .count::before,
.CX3 .calendar_Reservation .title .count::before {
  content: "[";
}

#CX3_POPOVER .title .count::after,
.CX3 .calendar_Reservation .title .count::after {
  content: "]";
}

#CX3_POPOVER .description .collapsedEvent {
  line-height: 115%;
  border-bottom: 2px solid silver;

  p {
    margin-top: 0;
    margin-bottom: 0;
  }

  .title {
    font-weight: bold;
  }

  .period {
    text-align: right;
  }

  .description {
    font-style: italic;
    white-space: pre;
    padding-left: 20px;
  }

  .location {
    font-style: italic;
    text-align: right;
  }
}

I had to play around with it a bit to get it just right, but you nailed it!

My calendar is a lot less cluttered now. Thank you for all your help!

thanks for adding maxEventLines: { row: line, row: line, … } .

But I am having trouble getting it to work.

		 {
           module: "MMM-CalendarExt3",
           position: "top_right",
           title: "",
           instanceId: '1',
		   config: {
             mode: 'month',
             carouselId: "basicCalendar",
             locale: 'en-ZA',
		     header: "",
             //headerTitleOptions: {month: 'long' , year:'numeric'},
		     eventTimeOptions: {timeStyle: 'short'},
		     useWeather: false,
             //maxEventLines: 1,
             firstDayOfWeek: 1,
		     displayEndTime: false,
		     useMarquee: true,
		     displayCW: false,
		     showMore: true,
		     showEnd: false,
		     weekIndex: 0, // From which week the view starts; -1 : last week, 0: this week 2: 2 weeks later, ...
		     //weeksInView: 5, // How many weeks will be shown from `weekIndex`
		     fontSize: "18px",
             eventHight: "20px",
		     calendarSet: ['Pieter', 'US_holiday'],
			 maxEventLines: { 4:6, 5:5, 6:4 , 7:3},
		   }
         },

I would expect this line maxEventLines: { 4:6, 5:5, 6:4 , 7:3}, to limit the number of rows based on the number of weeks so this month has 6 week rows so the entries in the cell should be limited to 4?

I even did a test case just to see if it would only make one line by doing this
maxEventLines: { 3:1, 4:1, 5:1, 6:1 , 7:1, 8:1}, and it did not work.

What am I missing.

thanks for your help.

Sorry, a hidden bug was only revealed in December—my fault. I fix it now. 1.9.4

GerrieD

@MMRIZE thanks for all your help.

I will update later and let you know if it worked.

GerrieD

@MMRIZE the updated fixed my issue.

thanks.

I’m working in the same situation: using an old iPad and trying to conserve space. I used this transform you posted way back in this thread:

/* In your config */
eventTransformer: (ev) => {
  if (!ev.isFullday) {
    let t = new Date(ev.startDate)
    let time = (t.getMinutes() === 0) ? String(t.getHours()) : String(t.getHours() + ':' + t.getMinutes())
    ev.title = `<span class="myTime">${time}</span> ${ev.title}`	
  }
  return ev 
}

That works great, but how can I get it to display the hour in 12h, not 24h?

sdetweil

@Decimeter9667 time see the eventTimeOptions

Decimeter9667

@sdetweil Hmm… are you sure that works in the context of the transform I showed? eventTimeOptions doesn’t seem to change it.

sdetweil

@Decimeter9667

you are doing it raw. Date.getHours() returns 0-23
so YOU have to check , and substract 12 if over 12

Decimeter9667

@sdetweil Thanks. For anyone else looking to do this, here’s how I modified the code:

        eventTransformer: (ev) => {
                    if (!ev.isFullday) {
                    let t = new Date(ev.startDate)
                    const amPm = t.getHours() >= 12 ? 'p' : 'a';
                    let time = (t.getMinutes() === 0) ? String(t.getHours() % 12 || 12) : String( (t.getHours() % 12 || 12)  + ':' + t.getMinutes())
                    ev.title = `<span class="myTime">${time}${amPm}</span> ${ev.title}`
                    }
                return ev
                }
