+    return {
+      dataSource: ds.cloneWithRows(_.range(25)),
+    };
+  },
+
+  render() {
+    return (
+      <ListView
+        dataSource={this.state.dataSource}
+        renderRow={this._renderRow}
+      />
+    );
+  },
+
+  _renderRow() {
+    var header = (
+      <View style={...}>
+        <Text>Click to Expand</Text>
+      </View>
+    );
+
+    var content = (
+      <View style={...}>
+        <Text>This content is hidden in the accordion</Text>
+      </View>
+    );
+
+    return (
+      <Accordion

+        content={content}
+        easing="easeOutCubic"
