Javascript 在嵌套的平面列表中响应本机Android Tv控件焦点导航

对于React，本机Android Tv Target无法为所有可触摸设备实现低于焦点的导航

为演示复制的步骤：：

以一个平面列表为例，其数据应包含a、B和C以及相应的数据。（简单的OTT主页列表，分别包含标题和转盘内容） 标题将是标题，数据将是另一个水平嵌套的平面列表。 例如：

const dummyArray = [{
id: 1, title: "A", data: [0,1,2,3,4,5,6,7],
id: 2, title: "B", data: [0,1,2,3,4,5,6,7],
id: 3, title: "C", data: [0,1,2,3,4,5,6,7]
}];

当我开始按下d'pad向下键时，假设我在A区（索引-2处），当我再次按下d'pad向下键时，它将进入B区（索引-2）。这就是它的实际行为，但我期待下面的行为。 预期行为：：它应该转到平面列表中每一行的起始索引

如果我想错了，有人能给我指出正确的道路吗
