How to create a submenu in Bitrix?

Question

1C-Bitrix

The question seems banal, but in my case, not everything is so simple. Or I'm just not well informed about this system.
As far as I know, in Bitrix the menu is formed according to the directory structure in the file system, you create a subsection on a specific page, check the box to create a menu, and it appears in the drop-down list.
But here's what I have on the site :
This is how the drop-down menu looks like:

And this is how the directory structure looks like:

I.e. the menu is formed not at all from the directory structure, but how is it formed then?
I need to do a banal thing, create a menu item About the company and name it certificates, but I can't do it. In the structure in general, both "services" and "promotions" and "payment" are inside "about the company", but the menu is formed somehow differently.

As far as I know, in Bitrix the menu is formed according to the directory structure in the file system, you create a subsection on a specific page, check the box to create a menu, and it appears in the drop-down list.

but you can add it yourself, by hand.
The documentation has a detailed description and examples of how to work with the menu.
In a simple case, the menu can be edited through the admin panel (or the file of the desired menu type .*.menu.php in the root of the site).
In a more complex (if a "multi-level" menu is used) - through standard tools or the .*.menu.php file in the root of the site and the .*.menu.php files in subfolders.

Answer 2

in Bitrix, you can create a submenu that does not match the section structure by adding

$aMenuLinks = Array(
  Array(
    "пункт 1", 
    "/link1/", 
    Array("/link1/"), 
    Array(
      "FROM_IBLOCK" => 1,
      "IS_PARENT" => 1,
      "DEPTH_LEVEL" => 1
    )
  ),
  Array(
    "подпункт 1", 
    "/sublink1/", 
    Array("/sublink1/"), 
    Array(
      "FROM_IBLOCK" => 1,
      "IS_PARENT" => 0,
      "DEPTH_LEVEL" => 2
    )
  ),
);

where the subclause must follow the parent. paragraph and have an appropriate nesting level

Answer 3

In Bitrix, the menu can be formed by components. That is, you may have a catalog or news folder with an index file that contains a complex component.
And this component takes information from the infoblock which has sections, subsections and elements.
Accordingly, you can set up the menu so that sections/subsections become menu items/sub-items.
And it won't affect the folder structure at all. Everything will be generated dynamically.

This is an old question, but I'll answer so I don't forget myself when I need it ))

1. in header.php or where the menu is included, you need to change the top menu type to horizontal_multilevel:
   

   <? $APPLICATION->IncludeComponent("bitrix:menu", "horizontal_multilevel", Array(

   
   
2. in .top.menu.php we write
   

   Array(
       "Пункт, из которого будет выпадать подменю",
       "/parent1/",
       Array(),
       Array(
         "FROM_IBLOCK" => 0,
         "IS_PARENT" => 1,
         "DEPTH_LEVEL" => 1
       ),
       ""
     ),
   /* подменю */
       Array(
         "Первый пункт подменю",
         "/submenu1/",
         Array("/submenu1/"),
         Array(
         "FROM_IBLOCK" => 0,
         "IS_PARENT" => 0,
         "DEPTH_LEVEL" => 2
         ),
         ""
       ),
       Array(
         "Второй пункт подменю",
         "/submenu2/",
         Array("/submenu2/"),
         Array(
         "FROM_IBLOCK" => 0,
         "IS_PARENT" => 0,
         "DEPTH_LEVEL" => 2
         ),
         ""
       ),
   /* конец подменю */
