class MyModel
{
/\*\*
\* @var StoreManagerInterface
\*/
protected $storeManagerInterface;
/\*\*
\* @param StoreManagerInterface $storeManagerInterface
\*/
public function \_\_construct(
StoreManagerInterface $storeManagerInterface
) {
$this-\>storeManagerInterface \= $storeManagerInterface;
}
/\*\*
\* Return IDs of root categories as an array
\*
\* @return array
\*/
public function getRootCategoryIds()

$ids \= \[\\Magento\\Catalog\\Model\\Category::TREE\_ROOT\_ID\];
foreach ($this-\>storeManagerInterface-\>getGroups() as $store) {
$ids\[\] \= $store-\>getRootCategoryId();

class MyBlock extends Template

Context $context,
MyModel $myModel,
array $data \= \[\]
