Javascript dropdown menu and Combo box problem.

[ha_shaikh]

In our web application(ASP.Net), we have database driven menus that are
of dropdown style on getting focus (a requirement). We've used
Javascript Menu Object for creating these menus. On different pages of
the application, we are using ASP.Net some DropDownLists. Now the
problem is that when any menu drops, these dropdownlists disappear as
long as the menu is dropped and reappear when the menu is folded back.
We are unable to find any reason and any solution for this. Can
somebody help us out of this?

Thanks in advance.
