Remarks
When this property is set to false
, the menu item is disabled and no pop-out image indicating child items is displayed. Setting this property to false
for a menu item essentially makes the menu item the end of that node, where no further levels are shown off of that node. The default value is true
.
If you want the menu item to show any child items, but to not be "clickable" itself, use the Selectable property and set it to false
.
