I want a accodion-menu. If the users hits one elment of the "outer"-menu it should succeed as follows:

if(this submenu is closed){
   1. open it
   2. close the other submenu
} else
{
  do nothing
}

It doesn't even react like this. So seems like I'm calling the wrong tag, with the .slideUp() function. Doesn't matter if I use slideUp() or slideDown() - please help :-)

Put this jQuery :

$(document).ready(function(){
   $('.outer').click(function () {
       $('.inner').slideUp();
       $(this).next().find('.inner').slideDown();
   });
});

It will slideUp all '.inner' classes and then it will select the good outer with $(this) selector, choose the elements after (I mean the ul), find all '.inner' classes and slide them down.

Wish it helped you.

EDIT : If you want the menu to be wrapped at the beginning, you can make it with Jquery :

$(document).ready(function(){
   $('.inner').slideUp();
   $('.outer').click(function () {
       $('.inner').slideUp();
       $(this).next().find('.inner').slideDown();
   });
});

or with CSS :

.inner{
    display:none;
}
