How to expand v-list-group in vuetify when child v-list-item is activated?

Question

Vue.js

Is it possible with standard vuetify solutions to make the v-list-group expand when the child v-list-item is activated?
I read the documentation, but either I'm stupid, or ..., but I don't understand how to implement it.
The only thing I found, you need <v-list-group :value="true">
to somehow automatically track the value?

Answer 1

I rummaged through the script code.
The question is closed. Who faced the same goal does not know how to do it, it is solved with the help of v-list-group group.
You write in it for example "admin" and all routes like "/admin/users", "/admin/backup" will activate v-list-group
