With the help of CategoryFactory you can get a collection of your categories, like so:

    public function getChildCategories($categoryId)
    {
        $category = $this->categoryFactory->create();
        $categoryCollection = $category->load($categoryId);

        //Get category collection
        return $categoryCollection->getCollection()
            ->addNavigationMaxDepthFilter()
            ->addUrlRewriteToResult()
            ->addIsActiveFilter()
            ->addAttributeToFilter('include_in_menu', 1)
            ->addAttributeToSelect(['name', 'url'])
            ->setOrder('position', 'ASC')
            ->addIdFilter($categoryCollection->getChildren());
    }

In your template you can then loop through the collection and build your mega menu.

  • Thanks for your reply. Do I need to add this code alongside the existent Topmenu.php or create a new Topmenu.php?
