+
+**实现方案**
+
+三分栏场景可以组合使用[SideBarContainer](../../reference/arkui-ts/ts-container-sidebarcontainer.md)组件与[Navigation组件](../../reference/arkui-ts/ts-basic-components-navigation.md)实现，SideBarContainer组件可以通过侧边栏控制按钮控制显示/隐藏，Navigation组件可以根据窗口宽度自动切换该组件内单/双栏显示，详情可参考[NavigationMode](../../reference/arkui-ts/ts-basic-components-navigation.md#navigationmode枚举说明)的属性。
