With ".mytheme_matrix_vertical_line" we can delimit cell "border color", but is there a way to delimit "day border" (ie 00h00) ?
One of the options is to add custom separators at the specified times (day starts): https://doc.daypilot.org/scheduler/separators/
Thank for your reply. For now, we have prototype this functionality through onBeforeRender(). We will tested this solution...
