Expanded 2nd-level menu Items are blocked by smaller window

Hi wayneljw,

Thank you for using WP Bootstrap Starter theme, you can fix that issue by adding this class in the menu “left-submenu” – https://www.screencast.com/t/PcU1Gi66njkS and add the css code below in the style.css

.dropdown-menu li.left-submenu > .dropdown-menu {
    left: -12.5rem;
    right: auto;
}
