Branch validation is the act of checking all parent branches when any tree item is toggled on or off.
itemClickToggleSelectEnabled
This property if true selects the tree item as if you clicked on the toggle button of the tree item.
toggledItems
Returns a list of toggled items from the current selected item. If no tree item is selected, then the toggled items are based off of the whole dataProvider.
toggleSelectType
There are three types of select types.
single
immediate
recursive
single
The single select type just selects the tree item that was clicked.
immediate
The immediate type selects all children of it on one level. This type has no effect if the tree item selected was not a branch.
recursive
The recursive type selects all children of the selected branch recursively.
