## Functions
properties
```kotlin
fun properties(
securePolicy: SecureFlagPolicy = SecureFlagPolicy.Inherit,
isFocusable: Boolean = true,
shouldDismissOnBackPress: Boolean = true,
) =
ModalBottomSheetProperties(
securePolicy = securePolicy,
shouldDismissOnBackPress = shouldDismissOnBackPress,
)
```
Properties used to customize the behavior of a [ModalBottomSheet](/jetpack-compose/androidx.compose.material3/material3/components/ModalBottomSheet).
#### Parameters
| | |
| --- | --- |
| securePolicy | Policy for setting `WindowManager.LayoutParams.FLAG_SECURE` on the bottom sheet's window. |
| isFocusable | Whether the modal bottom sheet is focusable. When true, the modal bottom sheet will receive IME events and key presses, such as when the back button is pressed. |
| shouldDismissOnBackPress | Whether the modal bottom sheet can be dismissed by pressing the back button. If true, pressing the back button will call onDismissRequest. Note that [isFocusable](/jetpack-compose/androidx.compose.ui/ui-test/functions/isFocusable) must be set to true in order to receive key events such as the back button - if the modal bottom sheet is not focusable then this property does nothing. |
