Why is my submenu dropdown extending off the page?

Hi everyone! I have been working on my site for around 3 months and haven’t had issues with my dropdown menus, but now my submenu dropdown goes off of the page and I want to make the wrapping width shorter, but no matter what I try it does not work.

This is what it looks like:

Notince how it extends past the page’s limits? I’m not sure how to fix that considering there is so much additional wrapping space.

Another issue I have been having is have no control over where the submenus show up after hovering.

Here’s what that looks like:

You can see that I am hovering on “Lloyd Flanders” but the submenu shows up beneath the main dropdown. I want it to show up directly to the right of what what is being hovered over. Ex: when I am hovering on Lloyd Flanders I want “All Season, Catalina, Contempo, etc” to show up directly to the right of “Lloyd Flanders”

If anyone can help that would be great!
