I'm trying to get a multiselect filter in a custom script to be able to use it in a custom REST API.

Although I can get all class-specific filterable attributes. But after applying the filter through parameters (for example, Size), the size attribute is removed from the list of attributes that can be filtered after application (default behavior of magento).

Need filters to behave in multiselection. I have tried to implement it using third-party module classes but without help.

Below my code

getObjectManager ();
$ state = $ obj-> get (Magento  Framework  App  State & # 39;);
$ state-> setAreaCode (& # 39; frontend & # 39;);

$ objectManager =  Magento  Framework  App  ObjectManager :: getInstance ();
$ categoryFactory = $ objectManager-> get (Magento  Catalog  Template  CategoryFactory & # 39;);
$ storeManager = $ objectManager-> get (Magento  Store  Model  StoreManagerInterface & # 39;);
$ resource = $ objectManager-> get (Magento  Framework  App  ResourceConnection & # 39;);
$ request = $ objectManager-> get (Magento  Framework  App  Request  Http);
$ params = $ request-> getParams ();
$ connection = $ resource-> getConnection ();
$ storeId = $ storeManager-> getStore () -> getId ();
$ categoryId = 824;

$ category = $ categoryFactory-> create () -> setStoreId ($ storeId) -> load ($ categoryId);
$ storeManager-> setCurrentStore ($ storeId);

$ filterableAttributes = $ objectManager-> get ( Magento  Catalog  Template  Layer  Category  FilterableAttributeList :: class);
$ appState = $ objectManager-> get ( Magento  Framework  App  State :: class);
$ layerResolver = $ objectManager-> get ( Magento  Catalog  Model  Layer  Resolver :: class);
$ filterList = $ objectManager-> create (
 Magento  Catalog  Model  Layer  FilterList :: class,
    [
        'filterableAttributes' => $filterableAttributes
    ]
)

$ layer = $ layerResolver-> get ();
$ layer-> setCurrentCategory ($ category);
$ allFilters = $ filterList-> getFilters ($ layer);

$ beforefinalFilters = [];
foreach ($ all filters as filter $) {
if ($ filter-> getName ()! = & # 39; Category & # 39; && $ filter-> getName ()! = & # 39;) {
if ($ filter-> getItemsCount ()) {
$ output = [];
foreach ($ filter-> getItems () as $ item) {
if ($ item-> getFilter () -> getData ("attribute_model")) {
$ flag = false;
$ code = $ item-> getName ();
$ name = strip_tags ($ item-> getLabel ());

$ beforefinalFilters[$code][]    = table (
& # 39; name & # 39; => $ name,
& # 39; value & # 39; => $ Item-> getValue (),
& # 39; code & # 39; => $ item-> getFilter () -> getAttributeModel () -> getAttributeCode (),
& # 39; isActive & # 39; => $ flag
)
}
}
}
}
}

echo "Before the filter:  n";
echo "
";
print_r ($ beforefinalFilters);
echo "
";

echo "------------------------------------------------ ---------------------------------- ";

echo "
";
$ applyFilters = array ();

foreach ($ all filters as filter $) {

if ($ filter-> getName ()! = & # 39; && $ && $ filter-> getName ()! = & # 39; && $ filter-> getItemsCount () && isset ($ params[$filter->getAttributeModel()->getAttributeCode()])) {

$ appliquedFilters[$filter->getAttributeModel()->getAttributeCode()]['label']    = $ filter-> getAttributeModel () -> getFrontendLabel ();

$ appliquedFilters[$filter->getAttributeModel()->getAttributeCode()]['value']    = isset ($ params[$filter->getAttributeModel()->getAttributeCode()])? $ params[$filter->getAttributeModel()->getAttributeCode()]: & # 39;

$ appliquedFilters[$filter->getAttributeModel()->getAttributeCode()]['filter']    = $ filter;

$ request-> setParam ($ filter-> getAttributeModel () -> getAttributeCode (), $ params[$filter->getAttributeModel()->getAttributeCode()])

}

}
foreach ($ applyFilters as $ key => $ value) {

$ filter = $ value['filter'];

$ filterValue = $ value['value'];

if ($ key == "price || $ key == & # 39;) & nbsp; & nbsp; & nbsp;

Carry on;

}other{

// apply the filter

// Magento  Catalog  Template  Layer  Filter  Attribute

$ filter-> apply ($ request);

}

}
$ collection = $ layer-> getProductCollection ();

$ collection-> getSelect () -> group (& # 39; e.entity_id & # 39;);
// get the filters after the application

$ allFiltersAfter = $ filterList-> getFilters ($ layer);
