Highlighting cells on a month level

[kansimies]

Hello,

I have tried to highlight weekends on a gantt with multiple zoom levels. I ran into an issue where the whole month as a cell gets highlighted if the month starts on a Saturday or Sunday.

Snippet can be seen here:

Currently I can go around this by checking the current zoom level, the problem is even bigger though if I apply the same styling to a timeline where the whole month gets highlighted.

@kansimies,
When you use the isWorkTime method and specify only the date parameter, Gantt uses the duration_unit parameter for the unit. So, for the month of week scale, you are checking if there is a working day of the specific date.
You can use the configuration object instead of the date, and specify the unit parameter:
https://docs.dhtmlx.com/gantt/api__gantt_isworktime.html#:~:text=date%20to%20check-,unit,-%2D%20(string)%20optional%2C%20a

Here is the updated snippet:

When the unit parameter is specified, Gantt checks if there is working time within that unit for the date, for example if there is any working day within a month. If there are no working days, the method returns false.
You can check that in the following snippet:
