Dear @Crossbow92
you could use CUSTOM CSS to style the menu like this. You could open and close it by clicking on an element. This element makes the styled menu visible with jQuery.
Hope that gets you in the direction.
Best!

You need to log in to your webspace in via FTP.
There you most likely are able to find the files.
If you are unsure how to go about this: just contact your webspace provider they are probably able to help you out.
