The GF_Field_Shipping class extends the GF_Field class, also known as the Field Object. This class is responsible for handling the Shipping field. Because Shipping fields are either a Single Method, Drop Down, or Radio Button, this class only adds some settings and sets the title for the field in the editor. The rendering of the Shipping field is handled by the class associated with its sub-type. The field “type” property will be set to “shipping” and the field “inputType” property will be “singleshipping”, “select”, or “radio”.

Settings and Properties
Settings control what options are available to the admin user when configuring the field in the form editor. Gravity Forms includes many built-in settings such as Field Label, Field Description, Choices, Conditional Logic, etc. In addition to built-in settings, custom settings can also be developed. For more information on how to develop custom settings and how to associate settings to a field, visit the GF_Field page.
Properties contain the values specified by the settings and generally are part of the Field Object.
The properties may be retrieved by accessing the Field Object as follows:
//get the field $field = GFFormsModel::get_field( $form, 1 ); //get the admin label $admin_label = $field->adminLabel;
The following settings are available for the field:
Controls whether the “Admin Field Label” setting appears.
Controls whether the “Enable Conditional Logic” setting appears.
Controls whether the “Custom CSS Class” setting displays. This allows a custom css to be used for the field.
Controls whether the “Description” setting appears. This allows a description for the field to be displayed.
Controls whether the “Field Label” setting which allows the label to be changed appears.
Controls whether the “Allow field to be populated dynamically” setting appears.
Controls whether the “Field Type” section displays. This allows the Shipping field to be set to the types: Single Method, Drop Down, Radio Button.
