   # If the service accepts entity IDs, target allows the user to specify entities by entity, device, or area. If `target` is specified, `entity_id` should not be defined in the `fields` map. By default it shows only targets matching entities from the same domain as the service, but if further customization is required, target supports the entity, device, and area selectors (https://www.home-assistant.io/docs/blueprint/selectors/). Entity selector parameters will automatically be applied to device and area, and device selector parameters will automatically be applied to area.

+### Filtering service fields
+
+In some cases, entities from a service's domain may not support all service fields. By
+providing a `filter` for the field description, the field will only be shown if at least
+on selected entity supports the field.
+
+The filter supports filtering on `supported_features` as well as on state attribute values
+in general.
+
+This is a partial example of a field which is only shown if at least one selected entity
+has the needed `supported_features`:
+
+```yaml
+  fields:
+    temperature:
+      name: Temperature
+      description: New target temperature for HVAC.
+      filter:
+        supported_features:
+          - climate.ClimateEntityFeature.TARGET_TEMPERATURE
+```
+
+This is a partial example of a field which is only shown if at least one selected entity's
+`supported_color_modes` attribute includes either `light.ColorMode.COLOR_TEMP` or
+`light.ColorMode.HS`:
+
+```yaml
+    color_temp:
+      name: Color temperature
+      description: Color temperature for the light in mireds.
+      filter:
+        attribute:
