When you want to change the responsible person, due date, status, and other fields of many tasks at once, use "Bulk Update". You can update or delete the selected tasks in one go.

| Who can use it | Available on |
|---|---|
| All | All |

*The bulk update button is not shown when you cannot edit tasks (for example, when viewing a public project). It is also not available on the cross-project screen or in Gantt-san.*

## Enter selection mode

Click the "Bulk update" :icon{name="lucide:square-check"} button in the header of the Gantt or List task list to enter selection mode. Checkboxes appear to the left of the tasks.

The header buttons appear when you hover over the header (they are always shown on touch screens). Click the "Bulk update" button again to leave selection mode and clear the selection. The Esc key also clears it.

## Select tasks

Click the checkboxes of the tasks you want to operate on. When you select the first one, the "Bulk Update" panel opens on the right.

- Hold Shift and click a checkbox to select the range from the last task you selected to that task.
- Even outside selection mode, Shift-clicking a task in the list enters selection mode and selects that task.
- Subtasks are not selected automatically. Select subtasks too if you want to update them.
- The panel stays open even if you deselect everything.

*Shift-clicking a bar on the Gantt chart is a selection for moving bars together. It is separate from the bulk update selection and is not a target for updating or deleting.*

## Update in bulk

Set only the fields you want to change in the panel. Fields left as "No change" stay as they are.

- Color: the bar color. Choose "Auto" to go back to the responsible person's color.
- Priority
- Milestone: choose "No milestone" to remove the milestone.
- Tags: **overrides** the tags of the selected tasks with the tags you enter. The previous tags are removed. If you enter nothing, tags are not changed.
- Responsible
- Ball
- Due date: sets the same period (start date to due date) on all selected tasks.
- Status

After setting the fields, click "Bulk Update". A confirmation lists the fields to update; click "Bulk Update" again to run it. "Reset" returns every field in the panel to "No change".

## Delete in bulk

Click "Bulk Delete" at the bottom of the panel to delete all selected tasks. **Subtasks are deleted together, and this cannot be undone.** In the confirmation, type "delete" to enable the delete button. Only owners and admins can delete in bulk.

## Difference from selecting on the Gantt chart

Shift-clicking bars on the Gantt chart to select several is for moving the bar dates together ([How to use the Gantt chart](002007000-gannt-chart)). When two or more are selected, a "Deselect" button appears.

Bulk update, on the other hand, is for setting the same value of fields such as responsible or status on the selected tasks, or for deleting them.
