Twitter Bootstrap multiple accordions but only one open panel at a time

Answer 1

The accepted answer is good, but doesn't exactly answer what they did in order to make that work.

In this fiddle you can see the bare-minimum code that's needed, which is:

 

    

        

             
First header
    
        
        

            
Content.
        
    
    

        

             
Second header

        
        

            
Other content.
        
    

Notice that each panel has a data-parent which targets the parent div with the ID #panels.

That is the magic sauce you need.
