Create a Simple Drop down menu

Hi there,

my blog is http://seattlestravels.com

I’ve been searching for a few hours and cannot find exactly what I am looking for.

My theme does not have a header widget, so I cannot get a plugin or widget to customize a drop down menu.

I do not want a side bar menu, I just want to add the drop down option onto my existing menu bar.

I am not educated in coding, so I am hoping to find a way to do this without getting into all of that.

Basically I have three menu items (travel gear, what to do, where to stay) and would like each one to have a few of their own items/pages in the drop down menu.

Thanks to anyone that can help 😀
