The Super Form supports the ability of linking fields. Using this feature you can set up some of the fields
to depend on other fields. Thus these dependent fields will be shown / hidden based on the state of the field they depend on.
For example some fields can be shown only when a check box is checked, otherwise they will be hidden.

This example showcases the use of a CheckBoxField ("Discontinued") that controls three other fields.
When "Discontinued" is checked, "UnitPrice", "UnitsInStock" and "UnitsOnOrder" are hidden.
These fields will become visible when "Discontinued" is unchecked.

Use the FieldsToEnable property of all the field classes to specify the collapsed fields that will be shown when the state of the field is changed.

Use the FieldsToEnable property of the CheckBoxField class to specify the collapsed fields that will be shown when the CheckBox is checked.
Use the FieldsToDisable property of the CheckBoxField class to specify the collapsed fields that will be hidden when the CheckBox will be checked.

Setting only these properties for the controlling fields will only make the controlled (dependent) fields be enabled / disabled.
In order to make the dependent fields be shown / hidden as well, you need to designate them as collapsable by setting their Collapsed property to true.
