In Views, how can you make a search like in most car listing website?

Hi,
I would like to make this search in Views…. Car Brand > Car Models under it. If I chose Toyota for example (parent search filter), the matching set of Car Models under the brand name Toyota will be visible (corolla, corona, pregio,… and so on). Amir said it would be part of a future feature but for now some JS would be involved.

Thanks
