using a jquery plugin in WordPress

Hello,

I’m very new in building a website.
I’m using backend editor with visual composer in a theme. I don’t know anything about codes. Hopefully you can help me out with a step by step guide to add the following plugin: ‘Responsive multi-level menu’

What must I do to get this jQuery plugin working into my WordPress site?

Can you help me?
