Problem of Combo Boxes overlapping menus in html

[shan blossom]

I am using Menus in my JSP pages.while menus are listed all other html properties are not overlapping the menu and menu is displayed correctly.If there is any combo box in the Jsp page then menu is not displayed correctly because the combo box is overlapping the menu list.
