Gantt View
A timeline view for project planning - drag to schedule, resize to adjust duration, visualise dependencies, and zoom between month and day granularity.
Gantt View displays your tasks as horizontal bars on a timeline, where each bar spans from the task's start date to its due date. It's the right view when you need to plan a project timeline, visualise how tasks overlap, manage dependencies between tasks, and adjust schedules by dragging bars around. Drag a bar left or right to reschedule; drag its edges to change the duration; see dependency arrows connecting tasks that must happen in sequence.
Gantt View is a Pro feature
The Gantt chart, including timeline visualisation, drag-to-resize, and dependency arrows, requires a Pro license. The other three task views (List, Board, Calendar) are available on every license. See License Settings.

How to open Gantt View
- View switcher: Click the Gantt option in the view switcher on the Tasks page toolbar (Pro).
- Saved view: Load a saved view captured while in Gantt View. See Task Filters & Sorting.
Things worth knowing
How tasks appear on the timeline
Each task is represented as a bar:
- Tasks with both start and due dates appear as full bars spanning that duration
- Tasks with only a due date (no start date) appear as point markers on the due date
- Tasks without any dates appear in a separate area - drag them onto the timeline to schedule them
Each bar shows the task name, assignee indicators, priority, and a progress indicator based on subtask/checklist completion. Completed tasks are clearly marked.
Drag-and-drop scheduling
Move a task: Click and drag a bar left or right. Both the start date and due date shift together, preserving the task's duration. Release to save.
Resize a task: Hover over the left or right edge of a bar until the cursor changes. Drag to adjust the start date (left edge) or due date (right edge) independently.
Schedule an unscheduled task: Drag a dateless task from the sidebar onto the timeline. It snaps to the time grid based on your current zoom level.
All changes save instantly on drop.
Dependencies - seeing the sequence
If tasks have dependencies set (blocked by / blocks), Gantt View draws arrows between the connected bars so you can see the sequence at a glance. This is the primary way to visualise a project's critical path - which tasks must finish before others can start.
Dependencies are managed from the Task Details Page or via the Task Dependencies picker. Gantt View visualises them; it doesn't create them (you add dependencies from the task itself).
Dependencies are also a Pro feature
Both the Gantt View and task dependencies require Pro. See Task Dependencies.
Two view modes - month and day
- Month view - day-level granularity across weeks and months. Best for project overviews and long-term planning where you need to see weeks or months at once.
- Day view - hour-level granularity within a single day or a few days. Best for detailed scheduling when tasks have specific times set.
Switch between them from the Gantt controls.
Zoom
Zoom in for more detail (each time unit takes more horizontal space) or zoom out for a wider overview (more time visible at once). The zoom level affects both month and day views.
Task list sidebar
Toggle the task list sidebar on or off from the toolbar. When visible, it shows a hierarchical list of your tasks (with subtasks indented under parents) alongside the timeline. Click a task in the sidebar to highlight it on the timeline; click a bar on the timeline to highlight it in the sidebar. The two stay synchronised.
Reorder tasks in the sidebar
Hover any task in the sidebar to reveal a drag handle, or grab the task's status colour dot - either one lets you drag the task to a new position and drop it between any two other rows. The list updates immediately and the order is saved with the task.
- Subtasks - drag a subtask within its parent to change the order of children.
- CRM tasks - CRM tasks (and their subtasks) in the Gantt sidebar can be reordered the same way as regular tasks, and the order is saved with each task.
- Pinned tasks stay on top - if you try to drag a task that's pinned, PrimeTask shows a short notice reminding you to unpin it first. Pins always take precedence over manual order.
One order, three views
The custom order you set in the Gantt sidebar is the same order you see in List View and the Project Tasks tab. Reorder once in any of these views and it reflects in the others.
The timeline only shows tasks with dates
The Gantt sidebar hides tasks that don't have a date. Tasks without dates still appear in List View and the Project Tasks tab - and if you add a date to a hidden task later, it shows up in the Gantt sidebar in its saved manual position.
Selection and bulk actions
Select tasks from the task list sidebar or from the timeline. A selection toolbar appears with bulk actions for status, priority, dates, and more. See Task Bulk Actions.
Filters and saved views
The same filter bar from List and Board views works in Gantt View - filter by status, priority, project, assignee, tags, and more. Your Gantt-specific configuration (view mode, zoom level, task list visibility) is captured when you save a view. See Task Filters & Sorting.
Filter by project for a clean project timeline
If you're planning one project, filter to that project first. The Gantt chart shows only that project's tasks, and the dependency arrows form a clear sequence from start to finish.
Best practices for Gantt
- Set both start and due dates - tasks need both to display as proper bars. Tasks with only a due date show as point markers.
- Use dependencies for tasks that must happen in sequence - the arrows make the critical path visible.
- Zoom out for planning, zoom in for scheduling - month view for the big picture, day view for precise timing.
- Review regularly - Gantt charts are most useful when they reflect reality. Update dates and dependencies as plans change.
Common questions
"My tasks aren't showing as bars - they're just dots."
Tasks need both a start date and a due date to appear as bars. If a task has only a due date (no start date), it shows as a point marker. Open the task and add a start date.
"How do I add a dependency between two tasks?"
Open either task's Task Details Page, go to the Dependencies section, and add the other task as a prerequisite (blocked by) or dependent (blocks). The arrow appears on the Gantt chart automatically. See Task Dependencies.
"Can I drag to create a dependency arrow directly on the Gantt?"
No - dependencies are created from the task detail page's dependency picker, not by drawing on the timeline. The Gantt view visualises dependencies; it doesn't create them.
"How do I schedule a task that doesn't have dates yet?"
Find the task in the task list sidebar (toggle it on if it's not visible). Drag the task from the sidebar onto the timeline at the desired position. PrimeTask sets the start and due dates based on where you drop it.
"I want to see only one project's timeline."
Filter by project using the filter bar. The Gantt chart shows only that project's tasks, with dependency arrows forming the project's sequence.
"The Gantt view seems empty."
Check your filters - you may be filtering out the tasks you want to see. Also check that your tasks have dates set (dateless tasks appear in a separate area, not on the main timeline).
"Why can't I drag a pinned task to a new position?"
Pinned tasks are anchored to the top of the list, so reordering them would conflict with their pin. Unpin the task first, then drag it to the position you want.
"Will my drag order survive restarts?"
Yes. The custom order is saved with each task and restored on the next launch - including for CRM tasks and subtasks. It's also shared with List View and the Project Tasks tab.
