+#### Use with entity-filter
+The `items` list can be populated by `entity-filter` using a trick:
+
+```yaml
+type: entities
+title: Entity Filter Fold
+entities:
+  - type: custom:hui-entity-filter-card
+    entities:
+      - light.bed_light
+      - light.ceiling_lights
+      - light.kitchen_lights
+    state_filter:
+      - "on"
+    card:
+      type: custom:fold-entity-row
+      head:
+        type: section
+        label: Lit lamps
+
+  - type: custom:hui-entity-filter-card
+    entities:
