Streaming category style learning adventure

Hi E-Learning Heroes community, 

I have been tasked with creating a digital binder with details about my company's lines of business. There are many "trees" or ways these LOBs branch into many specific services. I am hoping to get some guidance on how I should go about the design process/where I could start. My leadership is requesting a streaming type style for example: the way Netflix provides categories/genres to choice from. 

Any tips or suggestions are welcome and appreciated! 

Thank you!
