A pair of subVIs for connecting a cluster of enums and booleans to a set of options in a menu (either the right-click shortcut menu on control or the VI menu bar). Adding new menu options requires only dropping a new boolean or enum in the cluster.
See original conversation here.
I use this heavily in User Interfaces, with display options being accessed via the shortcut menus of graphs, tables, and listboxes, rather than being independent controls on the Front Panel.
Relies on the OpenG LabVIEW Data Library.
