There are several ways to do your menu based on your requirement.
Checkout our demo store - http://luggage.mycb.cloud
We made step by step videos on how we created the demo store. It is located at: http://www.connectedbusiness.com/t-documentation.aspx
The step by step videos are 1/2 way down the page on the right, and there is a video on navigation settings which can be directly viewed at https://vimeo.com/225952651
Note that our summer release will include a new menu builder!
Let us know if that helps!
