Hello
The "scrollable-menu" class appears incompatible with nested submenus. Removing it for Plugin submenu would allow a plugin to use SubMenus itself.
Use case: WeatherMap would list in a submenu all the weathermaps defined, allowing a quick access.
The patch for weathermap would come if this one is accepted.
Bye
