I understand this request may be complex, and if a solution isn’t feasible,

its just code, if you can do it in your head, then code can do it…

Sure, that’s doable. There’s no reason why it shouldn’t be possible.

This kind of work is domain analysis, which is basically my real-world job.

However, it’s not exactly simple. By simple, I mean it’ll take more than the usual 10 minutes I’d spend diving into this hobby project that genuinely interests me.

And honestly, my rate is quite high. :D (Just kidding.)

Let’s clarify a few things first.

CX3 is usually useful for viewing events from multiple calendars at once, so you’re probably using other types of calendars (e.g., personal meetings, family schedules) together. For this task, let’s assume that the target “customer reservation” events are in a separate, independent calendar. For convenience, I’ll call this calendar “Reservation” from now on.
Given the nature of calendars, I assume that there won’t be any overlapping events in the Reservation calendar. Additionally, I’ll assume there are no full-day events or events that span midnight.

With these assumptions, I’ll give it a shot sometime tomorrow when I have some free time. I can’t make any promises, so please don’t get your hopes up too high.

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

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.

@GerrieD
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?
