En Dis drop down menu.....

[Laint]

I need to set up a drop down menu that has the following:
En or Dis. I would like the background color of En to
turn blue when you select it; when selecting Dis its
background should turn to Red, additionally only when
selecting Dis, I want the text typed to the left of the
drop down menu to be completly removed.

Thanks,
Laint
