缺少WordPress自定义文章类型选择模板下拉列表

“我的主题”有3个不同的菜单(顶部、主菜单和页脚),所有这些菜单对每个菜单都具有相同的模板,例如:主菜单具有中心、东、西、北和南位置,具有相同的布局,顶部菜单也具有相同的布局。

主菜单和顶部菜单中的每个位置都是一个归档页面,在这里我可以显示该位置帖子的列表以供进一步查看。但是通过遵循传统的archive-{post_type}.php,我必须为每个位置创建一个新的归档页面。

以下是主菜单的代码:

[
    "capability_type" => "post",
    "description" => "Holds our location's specific data",
    "public" => true,
    "menu_position" => 5,
    "has_archive" => true,
    "show_admin_column" => true,
    "supports" => [
        "title",
        "editor",
        "thumbnail",
        "excerpt",
        "revisions",
        "page-attributes"
    ],
    "taxonomies" => [
        "post_tag"
    ],
    "labels" => [
        "name" => "Locations",
        "singular_name" => "Location",
        "add_new" => "Add Location",
        "add_new_item" => "Add Location" ,
        "edit_item" => "Edit Location",
        "new_item" => "New Location",
        "all_items" => "Locations" ,
        "view_item" => "View Location",
        "search_items" => "Search Location",
        "not_found" => "No Locations found",
        "not_found_in_trash" => "No Locations found in the Trash",
        "parent_item_colon" => "",
        "menu_name" => "Locations"
    ]
]

输出如下:

请帮助解决此问题。
