|Assignee:||J. Templ||% Done:|
Hierarchical menus, i.e. menu items that expand to a nested menu, should be added to the BlackBox distribution. An implementation for hierarchical menus by Juan Antonio Ortega is available from CPC as the CpcDropDown subsystem. It is proposed to integrate this subsystem into the standard distribution and to add support for keyboard shortcuts.
