+/// Allows the user to choose an item from a list of options.
+/// 
+/// 
+/// 
+/// The `GtkDropDown` displays the [selected]``selected(_:)``
+/// choice.
+/// 
+/// The options are given to `GtkDropDown` in the form of `GListModel`
+/// and how the individual options are represented is determined by
+/// a `Gtk.ListItemFactory`. The default factory displays simple strings,
+/// and adds a checkmark to the selected item in the popup.
+/// 
+/// To set your own factory, use `Gtk.DropDown.set_factory`. It is
+/// possible to use a separate factory for the items in the popup, with
+/// `Gtk.DropDown.set_list_factory`.
+/// 
+/// `GtkDropDown` knows how to obtain strings from the items in a
+/// `Gtk.StringList`; for other models, you have to provide an expression
+/// to find the strings via `Gtk.DropDown.set_expression`.
+/// 
+/// `GtkDropDown` can optionally allow search in the popup, which is
+/// useful if the list of options is long. To enable the search entry,
+/// use `Gtk.DropDown.set_enable_search`.
+/// 
+/// Here is a UI definition example for `GtkDropDown` with a simple model:
+/// 
+/// ```xml
+/// <object class="GtkDropDown"><property name="model"><object class="GtkStringList"><items><item translatable="yes">Factory</item><item translatable="yes">Home</item><item translatable="yes">Subway</item></items></object></property></object>
+/// ```
+/// 
+/// If a `GtkDropDown` is created in this manner, or with
+/// `Gtk.DropDown.new_from_strings`, for instance, the object returned from
+/// `Gtk.DropDown.get_selected_item` will be a `Gtk.StringObject`.

-/// ## Title Buttons
-///

+/// `Gtk.Image.new_from_file`, for instance:
+/// 
+/// ```c
+/// GtkWidget *image = gtk_image_new_from_file ("myfile.png");
+/// ```
+/// 
+/// If the file isn’t loaded successfully, the image will contain a
+/// “broken image” icon similar to that used in many web browsers.
+/// 
+/// If you want to handle errors in loading the file yourself, for example
+/// by displaying an error message, then load the image with an image
+/// loading framework such as libglycin, then create the `GtkImage` with
+/// `Gtk.Image.new_from_paintable`.
+/// 
+/// Sometimes an application will want to avoid depending on external data
+/// files, such as image files. See the documentation of `GResource` inside
+/// GIO, for details. In this case, ``resource(_:)``,
+/// `Gtk.Image.new_from_resource`, and `Gtk.Image.set_from_resource`
+/// should be used.

-/// trough node are a number of nodes with name block and style class .filled

-/// not in the navigation stack without having to keep a reference to it manually.
-/// 
-/// ## Header Bar Integration
-/// 
-/// When used inside `AdwNavigationView`, [class@HeaderBar] will automatically
-/// display a back button that can be used to go back to the previous page when
-/// possible. The button also has a context menu, allowing to pop multiple pages
-/// at once, potentially across multiple navigation views.
-/// 
-/// Set [property@HeaderBar:show-back-button] to `FALSE` to disable this behavior
-/// in rare scenarios where it's unwanted.
-/// 
-/// `AdwHeaderBar` will also display the title of the `AdwNavigationPage` it's
-/// placed into, so most applications shouldn't need to customize it at all.
-/// 
-/// ## Shortcuts and Gestures
-/// 
-/// `AdwNavigationView` supports the following shortcuts for going to the
-/// previous page:
-/// 
-/// - <kbd>Escape</kbd> (unless [property@NavigationView:pop-on-escape] is set to
-/// `FALSE`)
-/// - <kbd>Alt</kbd>+<kbd>←</kbd>
-/// - Back mouse button
-/// 
-/// Additionally, it supports interactive gestures:
-/// 
-/// - One-finger swipe towards the right on touchscreens
-/// - Scrolling towards the right on touchpads (usually two-finger swipe)
-/// 
-/// These gestures have transitions enabled regardless of the
-/// [property@NavigationView:animate-transitions] value.
-/// 
-/// Applications can also enable shortcuts for pushing another page onto the
-/// navigation stack via connecting to the [signal@NavigationView::get-next-page]
-/// signal, in that case the following shortcuts are supported:
-/// 
-/// - <kbd>Alt</kbd>+<kbd>→</kbd>
-/// - Forward mouse button
-/// - Swipe/scrolling towards the left
-/// 
-/// For right-to-left locales, the gestures and shortcuts are reversed.
-/// 
-/// [property@NavigationPage:can-pop] can be used to disable them, along with the
-/// header bar back buttons.
-/// 
-/// ## Actions
-/// 
-/// `AdwNavigationView` defines actions for controlling the navigation stack.
-/// actions for controlling the navigation stack:
-/// 
-/// - `navigation.push` takes a string parameter specifying the tag of the page to
-/// push, and is equivalent to calling [method@NavigationView.push_by_tag].
-/// 
-/// - `navigation.pop` doesn't take any parameters and pops the current page from
-/// the navigation stack, equivalent to calling [method@NavigationView.pop].
-/// 
-/// ## `AdwNavigationView` as `GtkBuildable`
-///

-/// [method@NavigationView.add] method.

 /// `AdwOverlaySplitView` is often used for implementing the

 /// pattern.
 /// 
-/// ## Sizing
 /// 
-/// When not collapsed, `AdwOverlaySplitView` changes the sidebar width
-/// depending on its own width.
-/// 
-/// If possible, it tries to allocate a fraction of the total width, controlled
-/// with the [property@OverlaySplitView:sidebar-width-fraction] property.
-/// 
-/// The sidebar also has minimum and maximum sizes, controlled with the
-/// [property@OverlaySplitView:min-sidebar-width] and
-/// [property@OverlaySplitView:max-sidebar-width] properties.
-/// 
-/// The minimum and maximum sizes are using the length unit specified with the
-/// [property@OverlaySplitView:sidebar-width-unit].
-/// 
-/// By default, sidebar is using 25% of the total width, with 180sp as the
-/// minimum size and 280sp as the maximum size.
-/// 
-/// When collapsed, the preferred width fraction is ignored and the sidebar uses
-/// [property@OverlaySplitView:max-sidebar-width] when possible.
-/// 
-/// ## Header Bar Integration
-/// 
-/// When used inside `AdwOverlaySplitView`, [class@HeaderBar] will automatically
-/// hide the window buttons in the middle.
-/// 
-/// ## `AdwOverlaySplitView` as `GtkBuildable`
-/// 
-/// The `AdwOverlaySplitView` implementation of the [iface@Gtk.Buildable]
-/// interface supports setting the sidebar widget by specifying “sidebar” as the
-/// “type” attribute of a `<child>` element, Specifying “content” child type or
-/// omitting it results in setting the content widget.
-/// 
-/// ## CSS nodes
-/// 
-/// `AdwOverlaySplitView` has a single CSS node with the name
-/// `overlay-split-view`.
-/// 
-/// It contains two nodes with the name `widget`, containing the sidebar and
-/// content children.
-/// 
-/// When not collapsed, they have the `.sidebar-view` and `.content-view` style
-/// classes respectively.
-/// 
-/// ```

-/// ├── widget.sidebar-pane
-/// │   ╰── [sidebar child]
-/// ╰── widget.content-pane
-/// ╰── [content child]

-/// When collapsed, the one containing the sidebar child has the `.background`
