How to display selected additional fields for different sections in Bitrix?

Question

PHP

Hello. On the site , you need to display the selected unique values ​​from the additional fields (Tags) of the sections (type - Binding to infoblock sections)

<div class="tags_cloud"><?
//$rsResult = CIBlockSection::GetList(array("SORT" => "ASC"), array("IBLOCK_ID" => "5"), false, $arSelect = array("UF_TAGI"));
$rsResult = CIBlockSection::GetList(array("SORT" => "ASC"), array("IBLOCK_ID" => $arParams["IBLOCK_ID"], "ID" =>$arResult["SECTION"]["ID"]), false, $arSelect = array("UF_TAGI")); 
if($arSection = $rsResult -> GetNext())
    { 
$uftag = $arSection["UF_TAGI"]; 
$ufcategory = $arSection["UF_CATEGORY"]; 

if($uftag) {
$arFilter = array('IBLOCK_ID' => 27,'ID' => $uftag);
$rsItems = CIBlockSection::GetList(array(),$arFilter);
echo '<div class="catalog-tags">';
while ($arItem = $rsItems->GetNext())
  { 
    echo '<div class="catalog-tags-item"><a href="'.$arItem['SECTION_PAGE_URL'].'">'.$arItem["NAME"].'</a></div>';	
  }
 echo '</div>';
  }
  
if($ufcategory) {
$arFilter = array('IBLOCK_ID' => 27,'ID' => $ufcategory);
$rsItems = CIBlockSection::GetList(array(),$arFilter);
echo '<div class="catalog-list-cat">';
while ($arItem = $rsItems->GetNext())
  { 
    echo '<div class="class="catalog-tags-item""><a href="'.$arItem['SECTION_PAGE_URL'].'">'.$arItem["NAME"].'</a></div>';	
  }
 echo '</div>';
  }

}
?></div>

The code works partially - the values ​​from the add. fields. BUT! They are the same for all sections. And they must be unique, as in the admin panel.
Below are links to sections and screenshots of additional. fields (Tags) from the admin panel. Sliding wardrobes

Amendment. The solution has been found!
In catalog.section.list and clear the cache

<? //Блок вывода Доп полей в разделах
$rsResult = CIBlockSection::GetList(array("SORT" => "ASC"), array("IBLOCK_ID" => $arParams["IBLOCK_ID"], "ID" =>$arResult["SECTION"]["ID"]), false, $arSelect = array("UF_TAGI")); 
if($arSection = $rsResult -> GetNext())
    { 
$uftag = $arSection["UF_TAGI"]; 

if($uftag) {
$arFilter = array('IBLOCK_ID' => 27,'ID' => $uftag);
$rsItems = CIBlockSection::GetList(array(),$arFilter);
echo '<div class="catalog-tags">';
while ($arItem = $rsItems->GetNext())
  { 
    echo '<div class="catalog-tags-item"><a href="'.$arItem['SECTION_PAGE_URL'].'">'.$arItem["NAME"].'</a></div>';	
  }
 echo '</div>';
  }
}
?>

The first code displays from the Add. fields (type - Binding to infoblock sections) selected sections that belong to only one category (that is, it does not take into account the values ​​of the admin panel, that other items are marked in another section).
And here is the code

<?
$IBLOCK_ID = 27; // ID нужного инфоблока

//Получаем все возможные поля текущего пользователя
$rsUser = CUser::GetByID($USER->GetID());
$arUser = $rsUser->Fetch();

//Выводим если множественное
foreach ($arUser['UF_TAGI'] as $propertyUf):
    echo $propertyUf;
endforeach;

//Создаем массив фильтра
$arFilter = array('IBLOCK_ID' => $IBLOCK_ID, 'ACTIVE' => 'Y');

//Добавляем наш массив в котором перечислены ID разделов выбранные пользователем
$sect_id = $fofilter;

//Создаем массив фильтра. В конце переменная фильтра
$arFilter = array('IBLOCK_ID' => $IBLOCK_ID, 'ACTIVE' => 'Y', 'ID' => $sect_id);

//Создаем массив выводимых полей
$arSelect = array('ID', 'NAME');

//Применяем метод с фильтром и полями
$rsSection = CIBlockSection::GetTreeList($arFilter, $arSelect);

//Выводим названия разделов
while ($arSection = $rsSection->Fetch()) {
    echo $arSection['NAME'];
}

foreach ($arUser['UF_TAGI'] as $propertyUf):
    $sectionsUser .= '\'' . $propertyUf . '\',';
endforeach;

eval('$fofilter=array(' . $sectionsUser . ');');
extract($fofilter);

?>

brings everything out.
