Theme menus

Hello there,
For some time I have been using the theme Origin as I wanted the option of having multiple navigation menus.
However, I have shifted to the Cubic theme as its more appealing to the eye, although the issue is it doesn’t have many navigation menus.
I was hoping for some advice/assistance to better my blog as it’s used for professional purposes and I’m hoping to gain traffic.
