This method does not return a value.
This method is part of IntegralUITreeViewService. A call to this method will trigger beforeCollapse and afterCollapse events. By handling beforeCollapse event you can prevent collapsing of specified item using your own custom conditions.
An item can also become collapsed by setting the expanded variable of item object to false. However, in this case only afterCollapse event will be fired.
If there is no specified item, all items in TreeView will become collapsed.
