vertical menu big space in between

I have big gaps in between each drop-down menu.

If you send me a url to view the page I can tell you the CSS to update in order to remove it.

Ok, Please check your PM.

It looks like an issue with chrome and how it displays list items. If you update menu.css and add:
display:block;

to the class:
#cssmw li

That should correct the problem.

Ok, this is what I found. Where do I add this code?

webroot / CSSMenuWriter / cssmw / menu.css

ul#cssmw {
cursor: default;
list-style-type: none;
margin: 0 0 0 0;
padding: 0 0 0 0;
}
ul#cssmw ul {
cursor: default;
list-style-type: none;
margin: 0 0 0 0;
padding: 0 0 0 0;
}
ul#cssmw ul li {
background-image: none;
float: none;
}
ul#cssmw li {
background-image: none;
float: left;
padding: 0 0 0 0;
position: relative;
white-space: nowrap;
z-index: 100;

}
ul#cssmw li ul {
display: none;
top: 0;
}
ul#cssmw li:hover > ul {
display: block;
position: absolute;
}

ul#cssmw li.hover > ul {
display: block;
position: absolute;
}

ul#cssmw li.current > ul {
position: absolute;
}
ul#cssmw > li {
background-image: none;
}
ul#cssmw > li > a {
background-color: #dadada;
background-image: none;
color: #713b8f;
display: block;
font-family: Arial, Helvetica, sans-serif;
font-size: 14px;
font-style: normal;
line-height: 41px;
margin: 0 0 0 0;
padding: 0px 0px 0px 0px;
text-align: center;
text-decoration: none;
width: 152px;

}
ul#cssmw > li > a:active {
background-color: #3d3d3d;
color: #fff;
text-decoration: none;
}
ul#cssmw > li:hover > a {
background-color: #bababa;
color: #000;
text-decoration: none;
}

ul#cssmw > li.hover > a {
background-color: #bababa;
color: #000;
text-decoration: none;
}

ul#cssmw > li.current > a.current {
background-color: #3d3d3d;
color: #fff;
text-decoration: none;
}

Update this:

#cssmw li {
float: left;
overflow: hidden;
}

to this:

#cssmw li {
float: left;
overflow: hidden;
display:block;
}

You can update it in the file:
/webassist/plugins/main_menu/menu.css

Thank You, Ray, Problem is fix.
