I did it with a stylesheet.
#gdm-plm-2 ul{
margin: 0;
padding: 0;
margin-bottom: 1em;
float: left;
}
#gdm-plm-2 ul li{
display: inline;
}
#gdm-plm-2 ul li a{
float: left;
color: black;
padding: 2px 2px;
text-decoration: none;
}
where gdm-plm-2 is the div id for that particular list.
The items in the list will need to have the , as part of the name ie: childpage1,
