if isDropdownVisible {
    // 显示切换下拉列表的代码
}

struct ContentView: View {
    @State private var isDropdownVisible = false
    @State private var items = ["Item 1", "Item 2", "Item 3"]

    var body: some View {
        List(items, id: \.self) { item in
            VStack {
                Text(item)
                if isDropdownVisible {
                    // 显示切换下拉列表的代码
                    Button(action: {
                        // 执行删除操作
                        items.removeAll(where: { $0 == item })
                        isDropdownVisible = false
                    }) {
                        Text("删除")
                    }
                }
            }
            .onTapGesture {
                isDropdownVisible.toggle()
            }
        }
    }
}
