object

A SftTreeItem object.

Preserve

Defines whether the expand/collapse state is restored. This argument is ignored if the Depth argument is True.

Preserve	Description
True	Restores the expand/collapse state of dependent items made visible, as saved by a previous call to Items.Collapse or Item.Collapse.
False	The expand/collapse state is not restored. Only the item itself is expanded and immediate dependents are made visible. They may be expanded or collapsed based on the Depth argument.

Depth

Defines the depth of the items to become visible.

Depth	Description
True	Expands all dependent items, including non-immediate dependent items. Preserve is ignored as all dependents are expanded.
False	Expands dependent items, based on the Preserve settings.

Comments

The Expand method expands the item so its dependents become visible.

The Expand method expands all dependent items of the item and restores the expand/collapse state of all dependent items, as saved by a previous Items.Collapse or Item.Collapse method call.

If the item is already expanded when using Expand, the item remains unchanged. It does not make any indirect dependents visible. To make sure that an item's indirect dependents are shown, use the Item.Collapse method first, which collapses the item (and all dependents), followed by Expand. Now all dependents are visible.
