I am a newbie so please bear with me and please let me know if i have not posted by question in right forum.

I am trying to create an e-learning website using buddypress courseware. I am thinking of using multisite. 1 site will be for home page, searching courses, other useful pages and blog. another site will be entirely for buddypress courseware. There will be a common global membership feature. I want to create a nice beautiful landing + search page from where students can explore courses. It should have good filtering options. This is pretty much how i want to create it https://www.udemy.com/discover/featured/ . Is there any plugin i am not able to find to do this or way to achieve it by customisation. Open for any kind of help/suggestions.
