Editing Checkboxes

<strong>Use BoostrapVue's checkbox:</strong>
<b-form-checkbox
  v-model="isBar"
>
  Bar
</b-form-checkbox>

Confusingly, it can also be <b-checkbox> (src).
Tab navigation. See Tab Key Navigation section. To navigate away from the dropdown, define the keydown event handler:
private onKeyDownFooCheckbox(e: KeyboardEvent) {
  this.emulateTab(
    e,
    () => {
      (this.$refs.barField as any).$el.focus();
      (this.$refs.barField as any).$el.select();
    },
    () => {
      (this.$refs.bazField as any).$el.focus();
      (this.$refs.bazField as any).$el.select();
    });
  }

Then add @keydown="onKeyDownFooCheckbox" define a method to set the keydown event listener on the checkbox and call it in mounted() callback:
private initializeKeyDownEvents() {
  (this.$refs.fooCheckbox as any).$el.parentNode.removeEventListener('keydown', this.onKeyDownFooCheckbox);
  (this.$refs.fooCheckbox as any).$el.parentNode.addEventListener('keydown', this.onKeyDownFooCheckbox);
}
