Hi, I have made great progress on the calendar configuration and css customization but i seem to have stuck on some details, if someone could help me out.

i am trying to achieve 3 weeks total, current week on top.
i am trying to get 2 or 3 lines per event, in order to see more text of event titles. i have managed that but i see now that more than one event per day overlap one on top of the other.

you can see events ok on Jun 28,29 but overlapping at other days.
i would appreciate any help.

@chriskar weekIndex:0

should set the first week shown in mode week

sdetweil

@chriskar views and scenes were config options in calendarExt2, but are not used in Ext3

chriskar

@sdetweil said in MMM-CalendarExt3:

@chriskar views and scenes were config options in calendarExt2, but are not used in Ext3

so i remove views and scenes and use only the config part?

sdetweil

@chriskar correct

mode:week
weeksInView:3
weekIndex:0 //first week to see, -1 is last week, default

etc

chriskar

ok thanks, this worked fine!
what about the overlaping issue? css code is mostly AI generated so it probably has a lot of junk in

sdetweil

@chriskar i do not know on css
he provides lots of control, but wrap seems difficult

Hi,
I updated to MM 2.32 this morning and ever since then, I have noticed that the CW entry in my MMM-CalendarExt3 is stuck at “CW1”:

I assume the newest changes have something to do with it

Any idea if I can solve this or do I need to wait for a module update ?
Thanks

sdetweil

@p1lspeda I see the same bug, but not sure where it is

a temp fix is to add this line to the CX3 config section

          minimalDaysOfNewYear:1,  // week number of 1st week in your country (should be 0 or 1)

there was an open issue on this inthe CX3 repo
https://github.com/MMRIZE/MMM-CalendarExt3/issues/215

I posted this workaround there too

@sdetweil
Great.
Thanks for help (again!)
