Change the lay out of the drop down menu

Hi Guys,

Hopefully someone can help me with the following.

Last week I’ve purchased the Enfold theme and imported the Gym Demo. Now I am struggling with changing the menu and especially the drop down menu. If you can please go to and put your mouse on ‘reisbestemmingen.’ You will now see a drop down menu with 4 continents of the world. I don’t want it stretched over the full width of my screen. I want to change it into a drop down menu in which all the continents are below each other. I also want to change some other things in the menu. I’ve searched on you tube videos and also in the enfold theme options at the header or general lay out but I can’t find the option to change it. Can you please advise on how I can change this? Thanks in advance!
