AnyLink Menu - trying to put menu items in unordered list

**mlr** · 08-18-2006, 05:13 PM

1) Script Title: AnyLink Drop-Down Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...pmenuindex.htm

3) Describe problem:
I am trying to use the menu as unordered list. However, in a long table, menus that are triggered on a link "below the scroll" don't work, and onclick the page jumps back to the top. Another problem is that sometimes I have to click more than once on the link to get the menu. If you copy the table rows in my example below until you get a scrollbar and scroll down to the last row, you will see how the page jumps back up. I don't know how to fix this.

Code:

I looked into this more and realized that if I leave the original onmouseover functionality, everything works. I just cannot get this to work with an onclick event.
