Hello @Randal , Please follow these steps to add this CSS code:

  1. Go to your Online Store
  2. Click on “Themes”
  3. Select “Edit code”
  4. Open your CSS file. If you have a custom CSS/Section CSS file, open that instead.
  5. If you can’t find your custom CSS file, open “base.css”
  6. Add the following code at the end of the file.
.mega-menu[open] .mega-menu__content ul.mega-menu__list.page-width.mega-menu__list--condensed {
    margin-left: 0;
    padding: 0 0 0 7px;
    right: 0 !important;
}
