Dependent Picklist

A Dependent Picklist provides the ability to define (or filter) a group of choices, based on a some other value.

About Dependent Picklists

These field display types can be used to build Dependent Picklists:

• Radio Buttons
• Picklists

For example, in manufacturing, a computer might be created from a few Sub Assembly items, each made up of available component parts. The Component Parts might be enumerated, based on inventory level, for example.

Example

Field Name	Field Display Type	Available Values
Sub Assembly	Picklist	External Case Assembly / Circuit Board Kit / Data Storage Devices / Ports and cables
Component Parts	Dependent Picklist (select Sub Assembly as Dependent Field)	ST-2342 / ST-99843 / ST-3209 / ST-0094 / FR-23432 / FR-6530 / FR-9093 / RF-234 / RF-235 / RF-237 / GTT-34534 / GTT-0779 / GTT-300567 / GTT-300595 / GTT-300827 / GTT-300857

The resulting Child Values are created based on associations created between Component Parts and the Sub Assembly Parent Value:

Considerations

• It is not possible to specify default values for a dependent picklist. (A separate default would be needed for each parent value.)

Using Dependent Picklists

Considerations

• After a dependent field association is created, the Use Label for grouping option cannot be enabled for any of the parent or dependent field values
• A field cannot be deleted if it is a "parent" for a dependent field
• If the "parent" field of a dependent field is changed, a confirmation message appears, requesting the user to acknowledge that data will be lost if the change is executed
• Dependent picklist values cannot be reordered

Add a Dependent Picklist

For each Dependent Picklist, a "parent" field is selected, which defines the top-level field in the dependency hierarchy. Additional values ("child" fields) are defined within the dependent picklist. The resulting dependent picklist is created by associating "child" field(s) with each "parent" field.

This is a two-step process; first, create the "parent" field, then create the Dependent Picklist (the "child" field).

1. Using the instructions in Fields, create a new field of any of the following types, add picklist values and save the field (this will be used as the parent field):
   • Radio Buttons
   • Picklists
2. Using the instructions in Fields, create a new field of type: Dependent Picklist, and enter the following information:

   The field label that will be displayed

   Display Type

   Dependent Picklist

   Parent Field

   • Select the "parent" field (created in the previous step)
   • Enter the picklist values

   Optionally, modify any of the remaining sections, using the instructions in Fields

3. Click [Save]

4. In the Enumerated Values section, click [Manage Values] to specify the collection of all possible values.

5. In the Dependent Picklist Associations section (at the bottom):
   • Click the [Add Associations] button.
   • Choose the Dependent Picklist Values to be associated with each Parent Value.
