#### Description [src]

    final class Adw.MultiLayoutView : Gtk.Widget
      implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget {
      /* No available fields */
    }

A widget for switching between different layouts.

`AdwMultiLayoutView` contains layouts and children. Each child has an ID, each layout has slots inside it, each slot also has an ID. When switching layouts, children are inserted into slots with matching IDs. The `GtkWidget:visible` property of each slot is updated to match that of the inserted child.

This can be useful for rearranging children when it’s difficult to do so otherwise, for example to move a child from a sidebar to a bottom bar.

The currently used layout can be switched using the `AdwMultiLayoutView:layout` or `AdwMultiLayoutView:layout-name` properties. For example, it can be done via a `AdwBreakpoint` setter to change layouts depending on the window size.

## AdwMultiLayoutView as GtkBuildable

The `AdwMultiLayoutView` implementation of the `GtkBuildable` interface supports adding layouts via `<child>` element with the `type` attribute omitted.

It also supports setting children via `<child type="ID">`.

Example of an `AdwMultiLayoutView` UI definition that can display a secondary child as either a sidebar or a bottom sheet.
