If you are using this menu onmouseover to display the drop downs and you want the links that, when you move your mouse over them cause the drop down to appear, to also be clickable links, all you need to do is configure their href attribute to a valid page (highlight green) and remove the onClick attribute (highlight red):
Code:
<a href="set this to a valid page" onClick="return clickreturnvalue()" onMouseover="dropdownmenu(this, event, menu1, '150px')" onMouseout="delayhidemenu()">Web Design</a>
