How to enhance metabase to support linkage drop-down filter?

Hi,

Anybody can tell how to enhance metabase to support linkage drop-down filter for the “question”?
suppose a drop-down box has options of Automotive Enterprises like {volkswagen, ford, Honda}, and another drop-down box lists all brand for the selected Enterprise, if “volkswagen” is selected, the second drop-down options should be {tiguan, golf, jetta}, if “ford” is selected, the second drop-down options should be {mondeo, focus}, …

Thanks

This has been discussed at length:

Current solution is via embedding in an IFRAME and handling the cascades outside of Metabase.

Thanks so much. You hit the point!

@guan You can upvote the main GitHub Issue #5540 concerning dependent/cascading filters and similar filter issues outlined here: Metabase 0.32 - RC1 is out

The more upvotes an issue receives the faster it is likely implemented as the Metabase team evaluates this when determining what issues are the most important to users. And cascading/dependent filters (#5540) could use every upvote it can get. This is the kind of basic filter ability that would make a huge impact for a great many users.
