I have an html tree which is mostly consisting of nested unordered lists.

I need to create a full width hover effect for each leaf, something similar with windows fi

I've had the same problem as you, after some trying and testing I came up with this. It allows you to add scrollbars and put the padding on the inner .

HTML


    
        
            
                Lorem ipsum dolor sit amet, consectetur adipisicing elit
            
            
                Lorem ipsum dolor sit amet, consectetur adipisicing elit
                
                    
                        Lorem ipsum dolor sit amet, consectetur adipisicing elit

CSS

.tree {
    position:relative;
    display: block;
    overflow: auto;
    border: 1px solid #8B9097;
    background-color: #fff;
    margin-left:200px;
    /*! margin-left: just for testing */
}
.tree > div {
    display:block;
    position:absolute;
    min-width:100%;
}
.tree * {
    white-space: nowrap;
}
.tree ul {
    margin:0;
    list-style-type: none;
    padding-left: 20px;
}
.tree li > div {
    position:relative;
    margin-left:-100000px;
    padding-left:100000px;
    border: 1px solid transparent;
    display:block;
}
.tree li div:hover {
    background-color: #B6BABF;
    color: #fff;
}
.tree li.collapsed > ul {
    display:none;
}

.tree li.expanded > ul {
    display:inherit;
}
