Examples in the docu dont work for me. They render but there is no functionality. https://next.vuetifyjs.com/en/components/list-item-groups/#list-item-groups

The codepen is directly taken from the vuetify documentation (first example). For me, the codepen doenst even render.

It doesn't exist anymore, you just need <v-list v-model:selected="selection"> and any v-list-item with a value will be selectable.

Could this please be in the documentation. It's impossible to guess.

Is there any way to make this return an object instead of an array?
