+## cl.arkui.1 List组件和Gird组件滚动条默认状态变更
+
+List组件和Gird组件滚动条默认状态从BarState.Off变更为BarState.Auto。
+
+**变更影响**
+
+List组件和Gird组件，如果没有设置滚动条状态，变更前不会显示滚动条，变更以后滚动时会显示滚动条，滚动停止两秒后滚动条隐藏。
+
+**关键接口/组件变更**
+
+List组件和Gird组件滚动条API接口文档：
+- [List组件属性](../../../application-dev/reference/arkui-ts/ts-container-list.md#属性)
+- [Grid组件属性](../../../application-dev/reference/arkui-ts/ts-container-grid.md#属性)
+
+**适配指导**
+
+对于不需要滚动条的场景，需要将List组件或Grid组件的scrollBar属性设置为BarState.Off。
+
+参考代码如下：
+```ts
+// xxx.ets
+@Entry
+@Component
+struct ListItemExample {
+  private arr: number[] = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
+
+  build() {
+    Column() {
+      List({ space: 20, initialIndex: 0 }) {
+        ForEach(this.arr, (item) => {
+          ListItem() {
+            Text('' + item)
+              .width('100%').height(100).fontSize(16)
+              .textAlign(TextAlign.Center).borderRadius(10).backgroundColor(0xFFFFFF)
+          }
+        }, item => item)
+      }
+      .width('90%')
+      .scrollBar(BarState.Off)
+    }.width('100%').height('100%').backgroundColor(0xDCDCDC).padding({ top: 5 })
+  }
+}
+```
