Answer
Solution:
Unfortunately css has no native 'hasParent' selector, but if you really do need pure-css you could try something like:
li {
position: relative;
float: left;
clear: left;
}
li > ul::after {
content: '';
position: absolute;
top: 5px;
right: 0;
width: 0;
height: 0;
border-top: 5px solid transparent;
border-left: 5px solid red;
border-bottom: 5px solid transparent;
}
<ul>
<li>lorem</li>
<li>lorem</li>
<li>lorem</li>
<li>lorem</li>
<li>
lorem
<ul>
<li>1</li>
<li>2</li>
<li>3</li>
</ul>
</li>
</ul>
