Editing attributes with subtypes and attribute domains

Subtypes and coded value domains provide drop-down lists in the Attributes window so you know that you are assigning the field a valid value. Any default attribute values can be populated when you choose a new subtype. Fields with subtypes or coded value domains that are being used to symbolize the layer are shaded in green in the Attributes window; any other subtype or coded value domain fields are shaded in gray.

The Attributes window does not actively assist you with entering valid values for range domains; you need to check that the attributes are valid after you have entered them.

Subtypes and attribute domains are available only for geodatabase data.

Steps:

1. Click the Edit tool on the Editor toolbar and select the features.
2. Click the Attributes button on the Editor toolbar.
3. Click the feature to edit at the top of the window and click the coded value domain or subtype field at the bottom of the window.
4. Click the value from the drop-down list. When the field is being used to symbolize the layer, click the ellipsis button to change the value and update the symbology.
Note:

When you change a feature's subtype, you are prompted about whether to change the existing values to the default values of the new subtype. If a field does not have a default value associated with it for the new subtype, its value remains unchanged.

5. To update a field with a range domain, simply type the new value.
