Sticky Submenus Menu Example
The "Sticky Submenus" Main Menu Group property is set to "Yes".
This property specifies whether the submenus close when the mouse moves away from the menu area or remain open until the user clicks somewhere else on the page.
The default behavior for the submenus is to close when the mouse moves away from the menu area. If you change this property to "yes", the submenus will only close if the user clicks somewhere on the page instead.
Sticky submenus behave exactly like the submenus in the Windows "Start" menu. They close if the user clicks somewhere outside the menu area.
Also see the "XP TABS" example above, which demonstrates a "super-sticky" behavior (one submenu always remains open if an option is selected).
