/** Choose an item from a list.
 *
 * %Gtk::DropDown is a widget that allows the user to choose an item
 * from a list of options. The %Gtk::DropDown displays the selected
 * choice.
 *
 * The options are given to %Gtk::DropDown in the form of Gio::ListModel,
 * and how the individual options are represented is determined by
 * a Gtk::ListItemFactory. The default factory displays simple strings.
 *
 * %Gtk::DropDown 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 set_expression().
 *
 * %Gtk::DropDown can optionally allow search in the popup, which is
 * useful if the list of options is long. To enable the search entry,
 * use set_enable_search().
 *
 * @par CSS nodes
 * %Gtk::DropDown has a single CSS node with name dropdown,
 * with the button and popover nodes as children.
