select box disappears when struts menu drops down

[peepio]

Hello,
I use struts menu for my application. I have html:select box is located just below the menu and on the left of the screen. Everytime I click on the item which has a submenu, the select box is disappeared. If I locate the select box on the right below the menu, then it is fine.

Please help. Thanks in advance.

It should be due to the buggy DHTML scripting they use for the menu painting.

I haven't used struts menu, but used a different third party menu program (Coolmenu - coolmenus.dhtmlcentral.com) and I observe the same problem of select box dissapearance when the focus goes on the Menu.
