Currently the specs have nested menu feature. Maybe sometime this can be integrated into vuetify.
Currently nesting in the left menu does not work.
Some Links:

https://material.io/guidelines/patterns/navigation-drawer.html#navigation-drawer-behavior
Related to
https://github.com/vuetifyjs/vuetify/issues/898
https://github.com/vuetifyjs/vuetify/issues/1830
Example inside Menu:
https://material.io/guidelines/components/menus.html#menus-menu-items

This is already possible, but probably doesn't follow the MD spec to the letter.
@KaelWD cool thats a starting point. i have a usecase inside left side bar (drawer) that is not possible atm
something like this (http://element.eleme.io/#/en-US/component/menu)

That looks like https://vuetifyjs.com/components/expansion-panels
You can see that the docs site uses them in its sidebar.
okay cool!
so its basically just a list inside drawer....
but deeper nesting isnt on the docs page... and currently not supported. or am i wrong?
default layout codepen with menu:

There is some buggy behaviour with the arrows on the right inheriting the wrong state, but that's a separate issue.
This has been split into #1877 and #1878 as they are separate components
@KaelWD @nekosaur thank you! stunning community & framework. happy patreon. cheers max
