Avada Theme - Submenu Customization

I just started using the Avada Theme in my wordpress site. I need to customize the menu on the left hand side. The items in the submenu should be shown below the parent item, not o

Solution 1:

To achieve this effect you would have to change the positioning of the submenu list from absolute to relative, and adjust it a bit e.g. in this way:

body.side-header-left #side-header #nav > ul > li > ul.sub-menu {                
    position: relative;
    right: auto;
    left: auto;
    top: auto;
    visibility: visible;
    opacity: 1;
    width: 100%;
    height: 0;
    overflow:hidden;
}
body.side-header-left #side-header #nav > ul > li:hover > ul.sub-menu,
body.side-header-left #side-header #nav > ul > li.current_page_item > ul.sub-menu {
    height: auto;
}
