Dropdown menu hangs off page

Hi, I'm struggling to get a dropdown menu to fit on the page, I'm not sure whether its an alignment issue, or if it is possible to make the text for the links break onto 2 lines?

Add this to Design > Custom CSS to move dropdown to left a bit

a.Header-nav-folder-title[href*="/blog"]+span {
    margin-left: -100px;
}
