Note: Rating field is part of the Survey add-on by the makers of Gravity Forms. Learn more about it here.
If you have the Survey add-on, you can have a lot of fun with the Rating field. With a Supercharged form, you can customize each instance of your Rating field with custom icons and colors, even images!
In the Appearance tab of your Rating field, you will find 3 new buttons. One to set the On Icon and Off Icon (you can use images as well.) If you want to use the default styles, simply click the Use Default button.
The On icon is the filled icon and Off icon is the empty icon.
You can use any icon from the added icon sets, use a custom icon or an image. This option works the same way as adding images or icons to radio button options.
