javascript - Multiple buttons in Twitter Bootstrap show the same dropdown - why? -

-

i trying put little dropdown menu bootstrap. put sample on jsfiddle here.

the idea have each button trigger different dropdown list, clicking on file gives dropdown containing new , close, clicking on edit gives dropdown containing copy, paste , undo , on.

however, same dropdown buttons. surely must have done wrong.

i had @ this jsfiddle, linked this stackoverflow question, doesn't seem work - no dropdown shows @ when clicking.

any suggestion?

here copy of html:

<div id="mainmenubar" class="btn-group">     <button class="btn" href="#" onclick="alert('hello!');">menu</button>     <button href="#" class="btn dropdown-toggle" role="button" data-toggle="dropdown">file</button>     <ul id="filemenuselector" class="dropdown-menu">         <li><a href="#">new</a></li>         <li><a href="#">close</a></li>     </ul>     <button href="#" class="btn dropdown-toggle" data-toggle="dropdown">edit</button>     <ul id="editmenuselector" class="dropdown-menu">         <li><a href="#">copy</a></li>         <li><a href="#">paste</a></li>         <li><a href="#">undo</a></li>                        </ul>     <button href="#" class="btn dropdown-toggle" data-toggle="dropdown">debug</button>     <ul id="debugmenuselector" class="dropdown-menu">         <li><a href="#">some debug</a></li>         <li><a href="#">show xml</a></li>         <li><a href="#">show log</a></li>         <li><a href="#">shut down lot</a></li>     </ul> </div>

i think need use links (anchors) inside buttons trigger dropdowns instead...

       <button class="btn btn-group">             <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">                 file                  <span class="caret"></span>             </a>             <ul class="dropdown-menu">                 <li><a href="#">new</a></li>                 <li><a href="#">close</a></li>             </ul>         </button>

here's working demo

edit: here's alternate version inside .btn-toolbar each dropdown inside own btn-group. works in firefox: http://bootply.com/61019
