Answer 1

Try this
<li class='sub'>
<a href='#'>Lorem ipsum </a>
<ul>
<li>
<a href='#'>
sub-item 1
</a>
</li>
</ul>
</li>
and in css add this
li.sub ul {
display:none;
position: absolute; left: 100%; top:0;}
li.sub:hover ul{
display: block;}
For creating new sub menus just add class='sub' to the < li> and add new < ul> below it as a child .
Example: http://jsfiddle.net/6kDG8/2/

Answer 2

Try this:
ul.dark_menu li ul li ul li { display: none; }
ul.dark_menu li ul li:hover ul li { display: block;}
ul.dark_menu li ul li:hover ul { left: 100%; top: 0; }
