How do I make WordPress query for Bootstrap tabs with subtabs?

[rolandas]

Basically what I’m trying to achieve would look like this: http://jsfiddle.net/nawg4mbc/8/

There’s my comment there: I can’t get post taxonomy slug assigned to it

I query all posts for top tabs, then I query children posts with get_pages(), but I have no idea how to get taxonomy slug.

Thanks in advance :)
