Add support for sub-sub-menus
|Reported by:||Viper007Bond||Owned by:|
Currently the only way to add multiple, grouped menu items is to create a new top-level menu. In most cases, this is overkill and inappropriate.
Some plugins have taken it upon themselves to make and style their own sub-sub-menu (such as SK2). They very widely and are inconsistent.
I propose adding core support for this. It shouldn't be too hard and it'd be very beneficial to us plugin developers.
