Can you suggest how to make menu.sections and UF_* friends?

Question

1C-Bitrix

It is necessary to make friends to display custom fields in menu items.
I understand that you need to customize the code of the menu.sections

component in the api requests component. OK . I added to make a request for all UF_*. in two places. What's next?)

if(!isset($arParams["CACHE_TIME"]))
  $arParams["CACHE_TIME"] = 36000000;

return $aMenuLinksNew;

Answer 1

Well, what's next, you need to add these UFs to the $aMenuLinksNew array, it is filled in a loop through $arResult["SECTIONS"], i.e. in order not to change something much, above after the request, in the while loop, $arResult["SECTIONS"] is filled in and add your UFs there.
Then where $aMenuLinksNew is filled, the last array

array(
      "FROM_IBLOCK" => true,
      "IS_PARENT" => false,
      "DEPTH_LEVEL" => $arSection["DEPTH_LEVEL"],
    ),

add it to it, in the menu component the values ​​will be in the PARAMS key
It is pointless to add UF to CIBlockElement::GetList
