Multiple UL's bullet style

[djp1988]

I have two UL lists one inside another, and the default li style is just rounded black for the first list and hollow black for the second, how can i force the child list to retain solid black dots as their style ?Thanks

<ul>  <li>item 1</li>  <li>item 2	<ul>	  <li>item 2 a</li>	  <li>item 2b</li>	</ul>  </li></ul>
