collapse (Windows)
collapse(objectOrName)
If the objectOrName is a tree or tree item, it is collapsed so that none of its child items (if it has any) are visible. If the objectOrName is a combobox, its pop-up list of items is hidden. (See also collapseItem(objectOrName, itemName), expandItem(objectOrName, itemText), and expand(objectOrName).)
