The field attributes do not display the domain drop-down list in ArcGIS Pro

Description

When a domain is applied to a field in ArcGIS Pro, the expected domain drop-down list in the attribute table is replaced by a text box. This issue complicates data entry by preventing users from selecting predefined values provided by the domain.

In this example, although a domain is assigned to the Status field, the domain drop-down list is not displayed in the attribute table.

Cause

The feature class contains a subtype field requiring a domain assigned at the subtype level. The domain drop-down list does not display subtypes without an assigned domain. For more information, refer to ArcGIS Pro: Apply a domain to a field.

Solution or Workaround

Use the Assign Domain To Field tool

1. Open the ArcGIS Pro project.
2. On the Analysis tab, in the Geoprocessing group, click Tools.
3. In the Geoprocessing pane, search for and click the Assign Domain To Field tool.
4. In the Assign Domain To Field pane, on the Parameters tab, specify the following parameters.
   1. For Input Table, select the feature layer.
   2. For Field Name, select the field to assign the domain to.
   3. For Domain Name, select the appropriate domain name.
   4. For Subtype, click Select All to apply the domain to all subtypes. Alternatively, check the check box in the list of subtypes to apply the domain to specific subtypes.
5. Click Run.

Assign a domain to each subtype in the Subtypes view

1. Open the ArcGIS Pro project.
2. In the Contents pane, select the feature layer. On the Data tab, in the Data Design group, click Subtypes.

Note:
Alternatively, in the Contents pane, right-click the feature layer and click Data Design > Subtypes.

3. In the Subtypes view, for the field to assign the domain to, double-click the Domain column for each subtype and select the domain name from the drop-down list.

4. On the Subtypes tab, in the Changes group, click Save.
