title: twitter bootstrap custom form selectbox
body: <p>I have looked through the twitter bootstrap components and can't find any custom form selectbox.
  I did find a Split button dropdowns component that looks like what I'm trying to style it like. The problem is I need the form to be able to submit the values of the option selected in the select box. 
  Is there a way I can use the Split button dropdowns and have it save the selected value to be submitted  by a form. </p>
