/// A [class@Gtk.ListBoxRow] used to reveal widgets.
/// 
/// <picture><source srcset="expander-row-dark.png" media="(prefers-color-scheme: dark)"><img src="expander-row.png" alt="expander-row"></picture>
/// 
/// The `AdwExpanderRow` widget allows the user to reveal or hide widgets below
/// it. It also allows the user to enable the expansion of the row, allowing to
/// disable all that the row contains.
/// 
/// ## AdwExpanderRow as GtkBuildable
/// 
/// The `AdwExpanderRow` implementation of the [iface@Gtk.Buildable] interface
/// supports adding a child as an suffix widget by specifying “suffix” as the
/// “type” attribute of a <child> element.
/// 
/// It also supports adding it as a prefix widget by specifying “prefix” as the
/// “type” attribute of a <child> element.
/// 
/// ## CSS nodes
/// 
/// `AdwExpanderRow` has a main CSS node with name `row` and the `.expander`
/// style class. It has the `.empty` style class when it contains no children.
/// 
/// It contains the subnodes `row.header` for its main embedded row,
/// `list.nested` for the list it can expand, and `image.expander-row-arrow` for
/// its arrow.
/// 
/// ## Style classes
/// 
/// `AdwExpanderRow` can use the [`.`](style-classes.html#property-rows)
/// style class to emphasize the row subtitle instead of the row title, which is
/// useful for displaying read-only properties.
/// 
/// When used together with the `.monospace` style class, only the subtitle
/// becomes monospace, not the title or any extra widgets.
