Change position of MenuBar

[guiiamorim]

Hi, I'm facing a problem when creating a MenuBar on a transparent window. I hoped that would be possible to place the menubar below my custom titlebar, but it shows above it. Is there a way to customize the position of the menubar?

fun App() {
    MaterialTheme {
        Box(
            modifier = Modifier.fillMaxSize()
                .background(Color.hsl(232F, .37F, .08F))
                .padding(8.dp),
        ) {
            Row(
                Modifier.fillMaxSize(),
            ) {
                Surface(
                    Modifier.weight(.7F)
                        .fillMaxHeight(),
                    shape = RoundedCornerShape(4.dp)
                ) {
                    Box(
                        Modifier.background(Color.hsl(232F, .38F, .12F))
                            .fillMaxHeight()
                            .padding(4.dp),
                    ) {

                    }
                }
                Spacer(Modifier.width(4F.dp))
                Surface(
                    Modifier.weight(2F)
                        .fillMaxHeight(),
                    shape = RoundedCornerShape(4.dp)
                ) {
                    Box(

If you use a custom titleBar, you should also implement a custom MenuBar yourself.

The built-in MenuBar by design is always attached to the top of the window, or to the top of the screen (depending on the OS).

Placing MenuBar in other places is only possible if we add a new standalone component, with its own design (you can create a separate issue for that).
