A SftTreeItems object.

FalseThe expand/collapse state is not preserved.


The Collapse method collapses all items so no child items are visible.

The Collapse method collapses all dependent items of all items and saves the expand/collapse state of all dependent items, so it can be restored by a subsequent Items.Expand or Item.Expand method call. The Collapse method visits each item on level 0 and collapses it. Items on other levels are not collapsed.

If a parent item is collapsed, subsequently adding child items will automatically expand the item.
