Is it possible when moving a event to take 15 minutes steps even in month or week view? so it works like snap to grid but with 15 minutes steps.
name: "Week", scale: "Day", navigatorMode: "week", cellWidth: 40,
Yes, it is possible. Please take a look at the following tutorial: https://code.daypilot.org/39403/javascript-scheduler-customized-snap-to-grid
Just remember that the smallest possible step is one pixel so you'd need to set the cellWidth to 96 (=4*24).
