Make other li elements wrap around when one li element height increases

Question

I am working on a drop down menu. Trouble that I am facing is that, I have a 3 level of <ul>, and in second level when height of a <li> increases because it was accommodating another <ul> then all other <li> of second level do not wrap around it.

You can visualize the situation in this Fiddle

when you hover your mouse over Technology then you would be able to see that size of Web Design <li> is greater because of another <ul> that it is accommodating, because of that Typography and Front end has dropped below. Is there any way to keep them wrapping around?

Html structure is like this:

<nav id="nav" role="navigation">
<ul class="clearfix">
    <li> <a href="?work"><span>Technology</span></a>
        <ul>
            <li><a href="#">Hot news</a></li>
            <li><a href="#">Sad news</a></li>
            <li><a href="#">Normal news</a></li>
            <li><a href="?webdesign">Web Design</a>
                <ul>
                    <li><a href="#">Super power</a>
                    </li>
                    <li><a href="#">Aim Gain</a>
                    </li>
                    <li><a href="#">Acheivers</a>
                    </li>
                    <li><a href="#">Lackers</a></li>
                </ul>
            </li>
            <li><a href="?typography">Typography</a>
            </li>
            <li><a href="?frontend">Front-End</a>
            </li>
        </ul>
    </li>
    <li><a href="?about">Personal Stuff</a>
    </li>
</ul>
