Remarks

Use the TreeViewOptions property to specify the shell combo box dropdown options.

All the possible values for this property are listed in the following table.

Value	Meaning
tvoContextMenus	Determines whether the shell context menus are displayed.
tvoHotTrack	Specifies whether the shell combo box dropdown items are hot-tracked when the mouse hovers over them.
tvoShowButtons	Specifies whether the expand buttons are displayed next to the parent dropdown items. If this option is deactivated, then the parent items can be expanded by double-clicking on them (if the tvoRightClickSelect option is True).
tvoShowLines	Specifies whether the tree lines are displayed within the shell combo box dropdown.
tvoShowRoot	Determines whether the expand buttons and the tree lines are displayed at the root level of the shell combo box dropdown.
tvoRightClickSelect	Specifies whether the property returns the right-clicked node when the control’s popup menu is invoked. This option also affects end-user capabilities in node selection and expansion. If set, the dropdown window remains open when selecting nodes using a left click. In addition, nodes can be expanded or collapsed via a double click, as an alternative to using expand buttons (see the tvoShowButtons option). If the option is not set, selecting a node via a left click automatically closes the dropdown window.

The default value of the TreeViewOptions property is [tvoContextMenus,tvoHotTrack,tvoShowButtons,tvoShowLines,tvoShowRoot].
