Field Dependencies

If you have a field with choices (Checkbox (Boolean), Radio buttons, Checkboxes, Single-choice list, Multiple-choice list), you can enable dependencies of other fields based on the choice(s). The choice field is called the master field, and fields that are dependent on it are called dependent fields.

Visibility dependencies

To make the visibility of a field dependent upon the values of a master field, do the following in the Library Edit screen:

  1. Create a master field with choice values (items) (or a Checkbox (Boolean) field).
    Example: Gender, with items Male and Female
  2. Add a dependent field, and select Dependencies of the field; this brings up the Dependencies list card.
  3. Press the blue plus (+) button to add a dependency; this brings up the Add a dependency card.
  4. Select the field upon which to be dependent and press the OK button; this will bring up the Create dependency card.
  5. Choose whether the dependency is only when editing an entry (the default) or also when viewing an entry.
  6. Then choose the value(s) (the items) of the master field that will cause the dependent field to be visible (say, Female) and press the checkmark in the upper-left corner of the card.

Now, when the corresponding choice(s) is|are selected (Female, perhaps), the previously hidden dependent field(s) become visible.

Value dependencies

The values of the following types of fields can vary depending on other fields: Radio buttons, Checkboxes, Single-choice list, Multiple-choice list.

When you create a value dependency, you set what values of the dependent field will be available for selection, for each possible value of the master field.

To make the values of a choice field dependent upon the values of a master field, do the following in the Library Edit screen:

  1. Create a master field with choice values (items) (or a Checkbox (Boolean) field).
    Example: Gender, with items Male and Female
  2. Add a dependent field, and select Dependencies of the field; this brings up the Dependencies list card.
  3. Press the blue plus (+) button to add a dependency; this brings up the Add a dependency card.
  4. Select the field upon which to be dependent and press the OK button; this will bring up the Create dependency card.
  5. Choose whether the dependency is only when editing an entry (the default) or also when viewing an entry.
  6. Then choose the value(s) (the items) of the master field that will cause the dependent field to be visible (perhaps Female) and press the checkmark in the upper-left corner of the card.
