[Rails-spinoffs] Expand divs

[Fabio Sussetto]

Hi, I'm using scriptaculous effects to make some divs apperar and 
disappear. I have three divs and I'm using the following code:

    <div id="barra1" 
onclick="Effect.toggle('subMenu1','slide',{duration:0.5});"></div>
            <div id="subMenu1" style="display:none;">
                    ......

then I have:

    <div id="barra2" 
onclick="Effect.toggle('subMenu2','slide',{duration:0.5});"></div>
                <div id="subMenu2" style="display:none;">
                .........

The code works, but I want that when a div is sliding down, the other 
two will close, so that there is only one div open at a time and not two 
or three expanded simultaneously.

Thanks for your help.
