v-selection

For manual selection You also need to set "single" or "multiple" selection to grid and manual selection to true for this to be useful For more how to work with selection go to here: selection functions

Select all only selects all on visible rows, so if filtered or grouped this will only highlight visable rows that can be seen when scrolling up and down. De-select will always deselect all

<v-grid-col>
  <v-header-template>
    <input v-selection="header" type="checkbox">
  </v-header-template>
  <v-row-template>
    <input v-selection="row" type="checkbox"
  </v-row-template>
</v-grid-col>

if you dont make a selection column you highlight with the help of shift and control buttons
