obtuve una respuesta de Alf Magne Kalleland - www.dhtmlgoodies.com
me dijo lo siguiente: Cita: Select boxes always appear on top of other elements
such as <div> in Internet Explorer. Iframe is known as a "windowed
element", while <div> and almost all other html tags are "windowless
elements". A windowed element will always appear on top of a windowless
element. y me dió el código de un ejemplo en el que se utiliza un iframe y un select. este ejemplo es el modificado que se puede encontrar en: http://www.dhtmlgoodies.com/scripts/...e-in-pane.html
Este es el ejemplo Modificado:
