Make entire clickable in Sugarcube

Hello,
I'm quickly falling in love with Sugarcube. My game looks 100x better already.

Here's a few more questions...

1. How do I make a <li> element (which has a list of radio buttons) clickable?

radiobutton {
	border: solid #000060 0.09em;
  white-space: 0.3em;
	padding: .45em 0.45em 0.45em 0.45em;  
	border-radius: 0 em;
  color:#ffffff;
	background-color:black;
	font-family: "Arial Black", "Gadget", sans-serif;
}

and

<ul>
<li><<radiobutton "$job" "1" checked>> 1</li>

<li><<radiobutton "$job" ""2"">> 2</li>

<li><<radiobutton "$job" "3">> 3</li>

</ul>

<<button "Choose my job" "Job Path">><</button>>

is my current code. I've tried a display: block but that didn't work. Any advice on this one?
