I have added the position (position-10 in my case) to the header block of the T3 BS3 Template and placed there the "topmenu" module.
So I want it looks like Tabs.
In the options of the menu module I have added the class "nav nav-tabs". But it didn't change.
Firebug plugin shows that it already has the class "nav nav-pills nav-stacked" for "ul" which become "nav nav-pills nav-stacked nav nav-tabs".
When I changing it in Firebug it works like I need.
Where is my mistake?
