JReviews offers 3 different types of custom field relations.

== Field option to Field option ==

With  this relation, when you select a field option of the parent custom  field, all fields that contain child field options will appear.

This  relation is useful for connecting Country, State and City custom  fields, you don't need to create one state field per country and one  city field per state. Only 3 custom field are required because we are  connecting field options.

For example, the 'United  States' field option of jr_country custom field will be saved as  '''Control Value''' for 'California' field option of jr_state custom  field which will be saved as '''Control Value''' for 'Los Angeles' field  option of jr_city custom field.

The relations are assigned on the Field Options Manager of the child custom field.
For example, when we add a new option for the City custom field, we need to assign the '''Control Value''':

== Field option to Field ==

With this relation, when you select a field option of the parent custom field, all child fields will appear.

This relation is useful when you want a child custom field to appear with all its values after parent field option is selected.

For  example, if you decided to create a different state field for each  country, you can assign a 'jr_usstates' custom field to 'United States'  field option of the jr_country custom field and the state field will  always show all its options.

Another example is to show  additional custom field with Restaurant Meals only after ''Yes'' value  has been selected for the parent Food custom field. In this case the  '''Control Value''' is assigned to the custom field on the field  Add/Edit screen:

== Field option to Field group ==

With this relation, when you select a field option of the parent custom field, all child field groups will appear.

This relation is useful when you want a whole field group to appear with all its fields after parent field option is selected.

For  example, if you have a 'Cuisine' custom field with field options  'French', 'Italian', etc., you can create a field group for each of  those field options that will show fields with more details about the  particular cuisine. In this case the '''Control Value''' is assigned to  the field group in Field Groups Manager:
