It’s possible that your custom theme has somehow hidden the regular stylings of the unordered lists. Perhaps your menu was styled by removing list-style-type on
list elements, but instead of styling a specific class or id, all list items were targeted.
Either way, here’s some CSS to get you started:
li {
list-style-type:circle;
margin:0 0 6px 24px;
}
I happen to like a little bit of a buffer between list items (which is where that 6px comes into play).
I hope that helps!
