Gantt marker format

How should Gantt markers be formatted. The “Today” marker renders, but the “Deadline” marker does not.

				{ text: "Today", css: "webix_gantt_today_marker", now: true },
				{
					text: "Deadline",
					start_date: "2022-08-30 00:00:00",
					css: "webix_gantt_today_marker"
				},

Good day @NathanO ,

start_date expects to receive a Date object, so you could convert your date string to the object:

{
	text: "Deadline",
	start_date: new Date("2022-08-30 00:00:00"),
	css: "webix_gantt_today_marker"
},

Of course, thanks, I was just working with “tasks” and had been entering dates as strings.
