    box-shadow: 2px 2px 6px rgba(0,0,0,.2);
    min-width: 12em; /* allow long menu items to determine submenu width */
    *width: 12em; /* no auto sub width for IE7, see white-space comment     

below */
}
.sf-menu a {

    text-decoration: none;

    /* only transition out, not in */
    -webkit-transition: none;
    transition: none;
}

/*** arrows (for all except IE7) **/
.sf-arrows .sf-with-ul {
    padding-right: 2.5em;
    *padding-right: 1em; /* no CSS arrows for IE7 (lack pseudo-elements) */
}
/* styling for both css and generated arrows */
/*.sf-arrows .sf-with-ul:after {
    content: '';
    position: absolute;
    top: 50%;
    right: 1em;
    margin-top: -3px;
    height: 0;
    width: 0;
    /* order of following 3 rules important for fallbacks to work */
    /*border: 5px solid transparent;
    border-top-color: #dFeEFF; 
    /*border-top-color: rgba(255,255,255,.5);
}
*/
.sf-arrows > li > .sf-with-ul:focus:after,
.sf-arrows > li:hover > .sf-with-ul:after,
.sf-arrows > .sfHover > .sf-with-ul:after {
    border-top-color: white; /* IE8 fallback colour */
}
/* styling for right-facing arrows */
.sf-arrows ul .sf-with-ul:after {
    margin-top: -5px;
    margin-right: -3px;
    border-color: transparent;
}
.sf-arrows ul li > .sf-with-ul:focus:after,
.sf-arrows ul li:hover > .sf-with-ul:after,
.sf-arrows ul .sfHover > .sf-with-ul:after {
}

Have anyone a solution for this bug? I want that the submenu have the same width like the parent menu item.

Answer 1

Please try this:

Remove width:700px from nav ul.

In your style.css line 943.

Answer 2

The width of 700px of the ul refers to the css style information

nav ul {
  height: 40px;
  margin: 0 auto;
  padding: 0;
  width: 700px;
}

You could avoid this with the css child selektor ( > ),

nav > ul {
}

but pay attention on words like "Rechenzentrum", that would be to long.

Answer 3

The min-width value is too much, you can change it to certain width like this one:

.sf-menu ul {
    box-shadow: 2px 2px 6px rgba(0,0,0,.2);
    width: 10em;
}
