Is there a way to disable the "selectable" property of a cell?
I would like to prevent the TimeRange Selection on certain slots, but in the BeforeCellRender event doesn't seems to be possible.
Maybe a client workaround?
At this moment it's only possible to disable the cells for the whole row by marking it as parent using PreventParentUsage. See also:
Disabling individual cells will be added in one of the future releases.
