Learn how to use the gantt collection display option

Gantt view is incredibly similar to the Timeline display option, but it allows you to show dependencies between timeline events. For example, track the tasks that preceded another task in a project, and which tasks will succeed it. This also means that when you drag a task to adjust the start and end, your dependant tasks will be updated too.

Date Formats

Depending on the type of date field you're using, Noloco will display your Gantt events differently. Date Time Fields

If your field has a date and time, then Noloco will (unless specified) display this in the user's local timezone. If you don't include an end date, the gantt event will default to one hour long.

A few examples of events with date times:

  • Meetings that start and end at specific times

  • Bookings that start and end at specific times

Date only Fields

If your field has only a date (and no time) then Noloco will display these as all-day events, using the date of the event, ignoring the user's timezone.

A few examples of events without dates:

  • Birthdays

  • Multi-day events such as conferences

  • Single-day events that don't have a specific start or end date

Mixing date-time fields with all day events:

If you need to display both variable time events and all-day events on the same calendar, it can be quite confusing to get this right with timezones.

But thankfully it is possible to do in Noloco.

Because you need to specify event start and end times, you'll need to use a date-time field.

But to indicate to Noloco that an event is an all-day event, regardless at timezone you can make the event start at midnight UTC (that's not your local timezone).

I.e. if you have an event that's meant to happen on February 1st, you would set the date to be 1st Feb 00:00 or as an ISO string 2023-02-01T00:00:00.000Z

Similarly, to indicate that it's an all-day event, you need to set the end-date to have the same value. That is to say, that the event is only on that day.

If an event needs to span multiple days, but be treated as an all-day event, regardless of timezone, you can adjust the end date to be on the last day of your event, but make sure it's time is midnight UTC (00:00) Below is an example where we mix all-day and specific event time events:

Grouping gantt events

You can group your events by any Single Option field, like a status or type. This produces distinct lanes for your events, to see how events overlap between lanes.
