Hello @meril

Sorry to inform you that currently the theme doesn’t have option for different menu for home page only.

However you can register a menu in functions.php file and need to play with some code in inc / hook / custom.php file inside education_hub_add_primary_navigation() function.

Alternatively, for you particular need you can always hire a customizer.
Fill up the form and send your details to hire a customizer http://wensolutions.com/#hire-customizer-form.

Hope this will give you some hint.

Regards!!!
