Important: If your choice labels contain any HTML or special characters such as ampersands, commas, hyphens or brackets of any type, you MUST enable the show values feature and give each choice a simple and unique value which does not contain any special characters. Failure to configure values could cause issues for features such as calculations, conditional logic, dynamic population, and validation.

Example: Changing the Button Display

The display of the radio button choices can be modified by using the gf_list category of CSS ready classes.

For example, to display the choices horizontally rather than vertically, enter the gf_list_inline CSS ready class in the field’s Custom CSS Class field under the Appearance tab.

This turns a multiple choice list into an inline horizontal list (not evenly spaced columns).
