Dropdown menu not working properly

Hi Everyone,

I’m kinda stuck on a really annoying problem and could really use some advice.

I’m having trouble with integrating the Jquery dropdown menu plugin into my new wordpress template. The plugin worked perfectly on another site, so I know it has got something to do with the template design.

The problem is that the dropdown menu actually becomes a drop-up ?? It seems like the dropdown menus are blocked by the item below it) Have a look here: https://www.coinlearninglab.com/wordpress/

I’ve tried a lot of different solutions, but can’t seem to fix it. Since I’m not really a programmer this has turned out to be a lot of frustrating trial-and-error attemps.

Any help would be much appreciated!
