I am trying to set up embroidery as a product on one of my sites to allow a customer to add custom printing and embroidery options to garments.

I am asking customers to choose the font of the words they require embroidering and have listed 5 radio style options of familiar fonts.

I have added a radio attribute for "other" fonts and i am trying to allow a text field to show up when that radio option is selected so that customers can type in their font.

Is it possible to mkae a radio attribute vlaue when selected open a text box up?
