Verás el resultado del script bajo esta línea poniendo el sursor sobre la categoría.

Este es el script que puedes seleccionar, copiar y pegar directamente.
Esta parte del script hay que pegarlo entre las etiquetas HEAD y /HEAD:

Esta parte del script hay que pegarlo entre las etiquetas BODY y /BODY, donde se quiera que aparezca el efecto:
<div id="popmenu" class="menuskin" onMouseover="clearhidemenu();highlightmenu(event,'on')" onMouseout="highlightmenu(event,'off');dynamichide(event)"> </div> <a href="#" onMouseover="showmenu(event,linkset[0])" onMouseout="delayhidemenu()">Enlaces 1</a><br> <a href="#" onMouseover="showmenu(event,linkset[1])" onMouseout="delayhidemenu()">Enlaces 2</a>
Hay que añadir el siguiente evento onload dentro de la etiqueta BODY:
onload=songticker()
