ExposedDropdownMenuBox

@Composable

expect fun ExposedDropdownMenuBox(expanded: Boolean, onExpandedChange: (Boolean) -> Unit, modifier: Modifier = Modifier, content: @Composable ExposedDropdownMenuBoxScope.() -> Unit)

Material Design Exposed Dropdown Menu.

Menus display a list of choices on a temporary surface. They appear when users interact with a button, action, or other control.

Exposed dropdown menus, sometimes also called "spinners" or "combo boxes", display the currently selected item in a text field to which the menu is anchored. In some cases, it can accept and display user input (whether or not it’s listed as a menu choice), in which case it may be used to implement autocomplete.

The ExposedDropdownMenuBox is expected to contain a TextField (or OutlinedTextField) and ExposedDropdownMenu as content. The menuAnchor modifier should be passed to the text field.
