How remove extra padding above Jetpack Compose OutlinedTextField?

Question

I'm trying to put OutlinedTextField into the Column after Box element like this

@Composable
fun Header() {
    Column {
        Box(
            modifier = Modifier
                .border(1.dp, Color.Cyan)
        ) {
            Text("Header")
        }

        OutlinedTextField(
            modifier = Modifier
                .fillMaxWidth()
                .border(1.dp, Color.Cyan),
            value = "",
            onValueChange = {},
            placeholder = {
                Text("Enter header")
            }
        )
    }
}

Borders added to see exact size of elements. It looks like this
with extra 8dp padding above, but when I use TextField instead of OutlinedTextField there are no extra space

@Composable
fun Header() {
    Column {
        Box(
            modifier = Modifier
                .border(1.dp, Color.Cyan)
        ) {
            Text("Header")
        }

        TextField(
            modifier = Modifier
                .fillMaxWidth()
                .border(1.dp, Color.Cyan),
            value = "",
            onValueChange = {},
            placeholder = {
                Text("Enter header")
            }
        )
    }
}

I need to know why it is happening and how to solve it

Version of library is "androidx.compose.material:material:1.0.0-alpha10"

Answer 1

The Padding above OutlinedTextField is there because the label moves to the top when in focus, which requires space.

If you don't want this feature, you can create your own outlined text field composable by modifying BasicTextField.
