How to begin the week in Monday in TimeLine

I’m using a timeline, I wonder if you can ever make that cell division always start on Monday. used

scheduler.config.start_on_monday = true;

but it did not work.

You can use =; scheduler.config.start_on_monday = true;

first line will apply the week start rules to timeline, second will define week starting day

If you need more control over starting day - you can redefine timeline_start with a custom function.

Thank you.
Worked properly.
Thank you for your attention.
