How to restrict draggable area in compose mail

In Compose Mail, you can restrict the draggable area by using the draggable attribute and specifying the bounds property. Here's an example:

import androidx.compose.foundation.Draggable
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.fillMaxWidth
import androidx.compose.foundation.layout.padding
import androidx.compose.material.Text
import androidx.compose.runtime.Composable

@Composable
fun RestrictedDraggableArea() {
    Column(
        modifier = Modifier
           .fillMaxWidth()
           .padding(16.dp)
    ) {
        Draggable(
            bounds = Modifier.width(200.dp),
            // Your content here
            content = {
                Text("Draggable area")
            }
        )
    }
}

In this example, the Draggable component is used to create a draggable area. The bounds property is set to Modifier.width(200.dp), which restricts the draggable area to a width of 200.dp. You can adjust this value to set the desired width.

You can also use bounds with Modifier.height or Modifier.size to restrict the draggable area in both directions.

If you want to restrict the draggable area to a specific region of the screen, you can use the bounds property with a Modifier that defines the region. For example:

Draggable(
    bounds = Modifier
       .width(200.dp)
       .height(100.dp)
       .offset(x = 100.dp, y = 100.dp),
    // Your content here
    content = {
        Text("Draggable area")
    }
)

This will create a draggable area that is 200x100dp in size and is offset by 100dp from the top-left corner of the screen.

Note that the bounds property only works when the Draggable component is used with a Column or Row layout. If you use it with a Box or other layout, it may not work as expected.
