Hide zip in addressfield form on commerce checkout pane? How can I hide some fields from addressfield module (for example zip code) on checkout process if certain country is selected?
E.G. If US country selected then hide postal code field. If CA country selected then show postal code.
Clive is correct. The module already adjusts the form as appropriate. If you aren't seeing this, you must have something interfering with the Ajax based update of the form element.
