[Vuejs]-VueJS2: Drop down menus and navigating away: If user returns to menu, how to pre-select the option he had chosen?

it’s possible to handle with router, but that not a good way, you should go with vuex, that best way, just create store, and dispatch after select value, and always get value when come on that component, that essay not that much difficult, let me know if you need but i know you can.
