Con HTML no lo podrás hacer, a fuerza hay que usar Javascript. Se puede hacer a mano, aunque quizá si ya usas jQuery puedes probar con esto: http://jqueryui.com/autocomplete/

Me sirve el ejemplo, pero no logro quitarle los mensajes que aparecen:

.attr( "title", value + " didn't match any item" )

y

.attr( "title", "Show All Items" )

Código:
