resizing the frame language choosing option

Hi,

I just published the multilingual apges of our site:

www.btg-ge.eu

Could you please advise me how to resize the length of the frame (in the top bar, right) that holds the language options (flags and letters). I'd like to have them automatically adjust to the place needed. Right now, the frame 's length is too large.

Thanks in advance.

Best,
Isabelle
