I tried to make changes in css to hide the scheduler bar over the non working days(Especially weekends) by changing z-index as a suggestion i got from bryntum scheduler forum.
https://bryntum.com/examples/gantt-for-extjs/kitchensink/#examples/ganttscheduler
.b-sch-timerange {
z-index: 10;
}
.
does the above css work only on vanilla js or should i do some more changes when it comes to EXT?.
