There is a component called v-switch that is placed inside a transition-group element. The v-switch component has a directive called v-foo, accepts a boolean prop called isOn and switches its template root according to the value of isOn. The v-foo directive has an inserted hook that should be called to ensure that the binding logic is refreshed whenever the template root changes.
