I got small problem:
li {width: 50%; float: left;}
ul.sub li {width: 100%;}
<ul>
<li>Test 1</li>
<li>Test 2
<ul class="sub">
<li>Test2.1</li>
<li>Test2.2</li>
<li>Test2.3</li>
<li>Test2.4</li>
<li>Test2.5</li>
</ul>
</li>
<li>Test 3</li>
<li>Test 4</li>
<li>Test 5</li>
<li>Test 6</li>
</ul>
How I can prevent those huge white empty space betwen Test 1 and Test 3 ? The best option would be that all main li elements would fit into that empty space.
Is that possible? Please HELP!
