ibnab / magento2-home-categories Goto Github PK

Thank you for your extension. It's very good.
Now, i want to use it for menu like Amazon (Departments button).
But i am a newbie in Magento 2...
How can i do this?
Please give me an advice.
Thanks.

thank you for the article , I did try to install the module but in frontend it has an error Setup version for module 'Ibnab_CategoriesSide' is not specified and tried adding 'Ibnab_CategoriesSide' => 1, to config.php and php bin/magento setup:upgrade then the added line is disappearing after run the command

This extension works well to show all store categories with their children on home page. The function
$categories = $this->getStoreCategories(true,false,true);
is used to fetch all categories and subcategories inside the root category.

But how to show categories and subcategories of a "specific category" (by id, or by url_key) on home page. I dont want all categories/subcategories of root-category of store.

Or, Is their any way to go one level down, like some kind of getStoreCategories(true,false,true, $level=2) will help to show categories of level 2 or 3 any input.
