    "西瓜",
    "苹果",
    "芝麻",

)
    "西瓜",
    "苹果",
    "芝麻",
    "狗熊"
)
 DropdownMenu(expanded = true, onDismissRequest = {
        }, modifier = Modifier.width(100.dp)) {
            datas.forEach {
                DropdownMenuItem(onClick = {
                    Log.e("tag", "吃：$it")
                    hasShow.value = false
                }) {
                    Icon(imageVector = Icons.Default.Favorite, contentDescription = "")
                    Text(text = it, modifier = Modifier.padding(start = 10.dp))
                }
            }
