Auswahlbox stöhrt Menu

[Raffi]

Hallo Leute

ich habe folgendes problem. Ich habe ein Menu, das mit der rechten maustaste geöffnet wird. Nun das Problem: Es wird überall angezeigt, ausser wenn es über ein Formularfeld (Dropdown) geöffnet wird, dann wird das DHTML Menu nicht korrekt angezeigt. Das Dropdown menu ist dann im DHTML Menu sichtbar (es schlägt durch).

Was kann ich da machen?
