Shows or hides the expand/contract symbols for items at indent level 0. The indent level 0 items become flush with the left side of the tree control when you hide the expand/contract symbols.

If you hide the expand/contract symbols, you can still expand or collapse an item at indent level 0 by double-clicking the item.

To disable the double-clicking functionality, wire a True constant to the Discard? parameter of the Item Close? event.
