CtkPopoverMenu is a subclass of CtkPopover that treats its
children like menus and allows switching between them. It is
meant to be used primarily together with CtkModelButton, but
any widget can be used, such as CtkSpinButton or CtkScale.
In this respect, CtkPopoverMenu is more flexible than popovers
that are created from a GMenuModel with ctk_popover_new_from_model().
To add a child as a submenu, set the “submenu” child property to the name of the submenu. To let the user open this submenu, add a CtkModelButton whose “menu-name” property is set to the name you've given to the submenu.
By convention, the first child of a submenu should be a CtkModelButton to switch back to the parent menu. Such a button should use the “inverted” and “centered” properties to achieve a title-like appearance and place the submenu indicator at the opposite side. To switch back to the main menu, use "main" as the menu name.

Just like normal popovers created using ctk_popover_new_from_model, CtkPopoverMenu instances have a single css node called "popover" and get the .menu style class.
CtkWidget *
ctk_popover_menu_new (void);
Creates a new popover menu.
Since: 3.16
void ctk_popover_menu_open_submenu (CtkPopoverMenu *popover,const gchar *name);
Opens a submenu of the popover
. The name
must be one of the names given to the submenus
of popover
with “submenu”, or
"main" to switch back to the main menu.
CtkModelButton will open submenus automatically when the “menu-name” property is set, so this function is only needed when you are using other kinds of widgets to initiate menu changes.
