title: Vuetify treeview - select parent without selecting children
body: <p>When using the treeview component from Vuetify, I am attempting to be able to select a parent <strong>without</strong> having it also select all of the descendants (children). I've tried various combinations of selectable, activatable, etc... but can't seem to find the appropriate combination. </p>
  
  <p>Anyone have any pointers for achieving this desired result?</p>
