A Picklist is a field that can contain a list of values. It appears as a dropdown list when displayed.
Create a Picklist
- Click Designer > Data > Objects > {object} > Fields
- Click [New Field]
- Provide the information in the sections below.
- Click [Save]
The field is added, and the field-definition is shown. You can now Manage and Reorder Values to specify display text and colors, images, and grouping labels.
Basic Information
- Specify the basic characteristics of the field:
- Label - The text that appears as the field name
- Display Type - Picklist
- Picklist Values - For a simple Picklist that returns the same values it displays, with no special colors, images, or groups for the display values, you can simply enter the values, as shown here:
- Otherwise, wait until the Picklist has been created, then Manage and Reorder Values.
- Maximum Storage Length - The String length of the longest value in the list.
- Use First Value as Default - Otherwise, the field is initially empty.
- Sort List Alphabetically - Otherwise, you manually arrange the order.
- Always Required - A selection must be made when adding or updating a record.
- Field Name - Automatically created by the system (but you can change it here)
Display Attributes
- Determine where the field is displayed in the default form, and whether or not the field is required when adding or updating a record.
Default Value
Default Value for an Enumerated Field
- If the value resolves to a string which is not in the list of enumerated items, the specified item is added, and is pre-selected in the list.
Role Based Permission Control
- Select a Role Based Permission Control for each of the roles in the list
Description Information
- Include a description of the field and it's use. This information is only visible to users with rights to customize this field.
Specify a Default Value

Manage and Reorder Values
Specify Display Text, Colors, Images, and Grouping Labels
The Enumerated Values section of the field-definition page lets you specify display-text, colors, images, and grouping labels, as well as the values returned by user selections:
Click [Manage Values] to specify display text, color, images, and grouping labels.
- Fields
- Alphanumeric Characters are allowed in labels and values, including special characters (+ / ' - _) and spaces.
- Display Label - The label to display in the list.
- Value - The actual value that is stored in a record (or returned to a program) when this item is chosen from the list.
- Image - Specify an image to display (learn more below)
- Show only Image in View mode - Whether to show the image alone, or together with the label.
- Font color - Foreground color
- Background color - Color of the area in which the text is displayed
- Use Label for grouping - The specified label becomes a heading in the list, rather than a selectable value (learn more below)
- Specify images
- To specify images, first upload them to the platform as Documents. This example shows records that were created after selecting such images from a picklist:
- Specify grouping labels
- Click Use Label for Grouping to use a label as a group indicator, rather than making it a selection the user can click.
- This option is useful when a picklist is long, and can be organized into groups.
- Considerations
-
- The Use Label for grouping option is available only for Picklists
- After the Use Label for grouping option is selected, the Sort List Alphabetically option is reset to No (otherwise, the label won't be helpful).
- If the Use Label for grouping option is selected, the enumerated values are not available for dependent field associations.
Reorder Values
In the Enumerated Values section of the field-definition page, click [Reorder Values] to change the order in which the values appear:
