question: usage of task groups #538

ab-smith · 2025-04-24T12:06:30Z

Hello,

First of all, thank you for your great work on this!

My questio 8000 n is regarding the expected behaviour (and target) of tasks groups. Based on #93 , I understood that we need to have something like this:

	let groups = [{ id: 'website', name: 'website' }];
	let tasks = [
		{
			id: '1',
			name: 'Redesign website',
			start: '2025-01-01',
			end: '2025-10-31',
			progress: 80,
			group_id: 'website'
		},
		{
			id: '2',
			name: 'Other stuff on the website',
			start: '2025-12-01',
			end: '2025-12-31',
			progress: 20,
			group_id: 'website'
		},
		{
			id: '3',
			name: 'Clean up the warehouse',
			start: '2025-10-01',
			end: '2025-12-31',
			progress: 50,
			group_id: 'warehouse'
		}
	];

	onMount(async () => {
		gantt = new Gantt('#gantt', tasks, {
			groups: groups,
			view_mode: 'Month',
			date_format: 'YYYY-MM-DD',
			infinite_padding: false,
			readonly_dates: true,
			readonly_progress: true,
			view_mode_select: true,
			holidays: [] //this is for disabling the grayed weekend
		});

		mounted = true;
	});

I was expecting a sticky column on the gantt where tasks of the same group will be on the same row.

wasn't this the intention? is it something you guys are working on or considering?

Thank you!

It seems that the idea of groups has come up a lot with this package. There was a PR #448 that was prepared to complete this. This has been updated in #528. When this is merged, you will have tasks within the same group on the same row.

From you screenshot, are you also expecting that there is some group label on the left of the gantt chart? This is something that I believe will be useful. However, it is not available yet.

Hello @stephenjmaher , thanks for the feedback. Indeed, having a label for that same « row » will make it much more convenient for multiple cases. No need for advanced nesting for now, just one level should be enough as a starting point.
I’ll monitor the two enablers in the meanwhile.

@stephenjmaher Hello! I also need the left-side labels.
Would it be possible to know when this feature might become available?
Is there any workaround I can use before the feature is officially released?
