Adding Text Input in a SELECT drop-down list

I have written, in an html form, a drop-downlist that uses <SELECT>: i.e. <SELECT NAME=state> <OPTION SELECTED>State <OPTION>AL <OPTION>AZ <OPTION> // and so on I would like a text input as the last option so that a user can type in a state (non-USA) and have this variable passed on. Is there any way of accomplishing this using html or php? Any help would be greatly appreciated, Tia, Andre -- Please pray the Holy Rosary to end the holocaust of abortion.
