Dropdown menu filter.

Hi,

We would like to build a search filter like below site:
http://bigfilter.com/en/
(Please Kindly check the bottom of the page)

There are two fields.
First field is category item
Second field is products item

When user select category 1. The second field will display it’s category produts list.

When user select category 2. The second field will display it’s category produts list.

We would like to build it on our homepage.
Is it possible to do it?

Also, Is it support multi-languages?

Thank you a lot!
