> ℹ️ > Macro (inline-media-image)

The following settings can apply to a Box type:

<u>Sequentiality:</u>

- Overlapping allowed - periods set for Boxes of the same type can overlap. The rule applies to the same-level Boxes in the hierarchy.
- Sequential - periods set for Boxes of the same type cannot overlap. The rule applies to the same-level Boxes in the hierarchy.

<u>Period Mode:</u>

- Manual - period of a Box is always set manually (no auto-scheduling adjustment).
- Auto top-down - period of a Box is set manually and restricts the periods of its Sub-Boxes.
- Auto bottom-up - period of a Box changes to encompass its Sub-Boxes.
- Auto scope-based - period of a Box changes to encompass tasks in its scope.

## Manual change of start/end date of a Box

You can set up a start/end date of a Box during the creation process. Time Periods of Boxes can be adjusted either:

- directly in Box Configuration > General > Basics
- in the Overview module.

The start/end dates of the Home (root) Box can't be changed - they are based on the duration of Boxes in the tree structure:

- start date = the earliest start date of a child Box
- end date = the latest end date of a child Box
