I need to add custom attribute same as image in backend in customer information to individual customer. If admin select category customer able to show only selected category.

namespace MetizsoftAllowcustomerModelConfigSource;

use MagentoFrameworkOptionArrayInterface;

class Category implements ArrayInterface

 protected $_categoryHelper;
 protected $categoryRepository;
 protected $categoryList;

 public function __construct(
 MagentoCatalogHelperCategory $catalogCategory,
 MagentoCatalogModelCategoryRepository $categoryRepository
 )
 
 $this->_categoryHelper = $catalogCategory;
 $this->categoryRepository = $categoryRepository;
 

 /*
 * Return categories helper
 */

 public function getStoreCategories($sorted = false, $asCollection = false, $toLoad = true)
 
 return $this->_categoryHelper->getStoreCategories($sorted , $asCollection, $toLoad);
 

 /* 
 * Option getter
 * @return array
 */
 public function toOptionArray()
 


 $arr = $this->toArray();
 $ret = [];

 foreach ($arr as $key => $value)
 

 $ret[] = [
 'value' => $key,
 'label' => $value
 ];
 

 return $ret;
 

 /*
 * Get options in "key-value" format
 * @return array
 */
 public function toArray()
 

 $categories = $this->getStoreCategories(true,false,true);
 $categoryList = $this->renderCategories($categories);
 return $categoryList;
 

 public function renderCategories($_categories)
 
 foreach ($_categories as $category)
 $i = 0; 
 $this->categoryList[$category->getEntityId()] = __($category->getName()); // Main categories
 $list = $this->renderSubCat($category,$i);
 

 return $this->categoryList; 
 

 public function renderSubCat($cat,$j)

 $categoryObj = $this->categoryRepository->get($cat->getId());

 $level = $categoryObj->getLevel();
 $arrow = str_repeat("---", $level-1);
 $subcategories = $categoryObj->getChildrenCategories(); 

 foreach($subcategories as $subcategory) 
 $this->categoryList[$subcategory->getEntityId()] = __($arrow.$subcategory->getName()); 

 if($subcategory->hasChildren()) 

 $this->renderSubCat($subcategory,$j);

 
 

 return $this->categoryList;
 

You cannot use MagentoFrameworkOptionArrayInterface type for as Source Model of a multi-select EAV attribute.

MetizsoftAllowcustomerModelCustomerAttributeSourceHideCategory

Should be extended MagentoEavModelEntityAttributeSourceAbstractSource or your class will be the interface of MagentoFrameworkDataOptionSourceInterface.

InstallData.php code attribute create code must have source model and backend model that

 $customerSetup->addAttribute(MagentoCustomerModelCustomer::ENTITY, 'hide_category', [
 'type' => 'varchar',
 'label' => 'Hide Categories',
 'input' => 'multiselect',
 'source' => 'MetizsoftAllowcustomerModelCustomerAttributeSourceHideCategory',
 'required' => false,
 'visible' => true,
 'position' => 333,
 'system' => false,
 'backend' => 'MagentoEavModelEntityAttributeBackendArrayBackend'
 ]);

Source Model Class code

<?php


namespace MetizsoftAllowcustomerModelCustomerAttributeSource;

class HideCategory extends MagentoEavModelEntityAttributeSourceAbstractSource

 /**
 * @var MagentoCatalogModelResourceModelCategoryCollectionFactory
 */
 private $collectionFactory;
 /**
 * @var MagentoCatalogHelperCategory
 */
 private $catalogCategory;

 public function __construct(
 MagentoCatalogHelperCategory $catalogCategory,
 MagentoCatalogModelResourceModelCategoryCollectionFactory $collectionFactory 
 ) 

 $this->catalogCategory = $catalogCategory;
 $this->collectionFactory = $collectionFactory;
 
 /**
 * getAllOptions
 *
 * @return array
 */
 public function getAllOptions()
 
 $options = $this->optionDataInArray();
 array_unshift($options, ['value' => '', 'label' => __('Please Selec')]);
 $this->_options = $options;

 return $options;
 
 public function optionDataInArray(): array 

 $categories = $this->catalogCategory->getStoreCategories(true, false, true) ; 
 $options = [];
 foreach ($categories as $category) 
 $options[] = ['value' => $category->getId(), 'label' => $category->getName()];
 $options =$this->secondLevelCategories($category->getId(),$category->getName(),$options);
 
 return $options;
 
 private function secondLevelCategories($parentCatId,$parentCatName,$options)
 

 $categoryCollection = $this->collectionFactory->create();
 $categoryCollection->addAttributeToSelect(
 'url_key'
 )->addAttributeToSelect(
 'name'
 )->addAttributeToSelect(
 'all_children'
 )->addAttributeToSelect(
 'is_anchor'
 )->addAttributeToFilter(
 'parent_id',
 $parentCatId
 )->addAttributeToFilter(
 'is_active',
 1
 )->setOrder(
 'position',
 MagentoFrameworkDBSelect::SQL_ASC
 )->joinUrlRewrite();

 foreach($categoryCollection as $category)
 $options[] = ['value' => $category->getId(), 'label' => $parentCatName.'-->'. $category->getName()];
 
 return $options;
 

Also, your module must have below files & folders structure.

InstallData.php full code

<?php

namespace MetizsoftAllowcustomerSetup;

use MagentoFrameworkSetupInstallDataInterface;
use MagentoFrameworkSetupModuleContextInterface;
use MagentoFrameworkSetupModuleDataSetupInterface;
use MagentoCustomerModelCustomer;
use MagentoCustomerSetupCustomerSetupFactory;

class InstallData implements InstallDataInterface


 private $customerSetupFactory;

 /**
 * Constructor
 *
 * @param MagentoCustomerSetupCustomerSetupFactory $customerSetupFactory
 */
 public function __construct(
 CustomerSetupFactory $customerSetupFactory
 ) 
 $this->customerSetupFactory = $customerSetupFactory;
 

 /**
 * @inheritdoc
 */
 public function install(
 ModuleDataSetupInterface $setup,
 ModuleContextInterface $context
 ) 
 $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);

 $customerSetup->addAttribute(MagentoCustomerModelCustomer::ENTITY, 'hide_category', [
 'type' => 'varchar',
 'label' => 'Hide Categories',
 'input' => 'multiselect',
 'source' => 'MetizsoftAllowcustomerModelCustomerAttributeSourceHideCategory',
 'required' => false,
 'visible' => true,
 'position' => 333,
 'system' => false,
 'backend' => 'MagentoEavModelEntityAttributeBackendArrayBackend'
 ]);

 $attribute = $customerSetup->getEavConfig()->getAttribute('customer', 'hide_category')
 ->addData(['used_in_forms' => [
 'adminhtml_customer',
 'customer_account_create',
 'customer_account_edit'
 ]
 ]);
 $attribute->save();
 

Output on magento 2 sample data Instance
