Hi!
There are small bugs with the link:

• The label is http://http://bootstrapdocs.com/v3.0.2/docs/components/#btn-dropdowns and should be
  http://bootstrapdocs.com/v3.0.2/docs/components/#btn-dropdowns
• The link is http//bootstrapdocs.com/v3.0.2/docs/components/#btn-dropdowns and should be
  http://bootstrapdocs.com/v3.0.2/docs/components/#btn-dropdowns

Cheers
