CSS Overlaps Menu Navigation Links

On media query with a max-width of 768px, the sub-menu under the About Menu overlaps to the Course Menu, I will want it pushed down on-click to display the sub-menu. I have tried a lot of options but is not working. Any help will be much appreciated.

var navLinks = document.getElementById("navLinks");

function displayMenu() {
navLinks.style.right = "0";
}

function hideMenu() {
navLinks.style.right = "-200px";
}
nav{
    display: flex;
    align-items: center;
    padding: 2% 6%;
    justify-content: space-between;
}

.nav-links{
    flex: 1;
    text-align: right;
}

.nav-links ul li{
    display: inline-block;
    padding: 8px 12px;
    position: relative;
    list-style: none;
}

.nav-links ul li a{
    color: #000;
    text-decoration: none;
    font-size: 15px;
}

.nav-links ul li::after{
    content: "";
    width: 0%;
    height: 2px;
    background:  #ff5733;
    display: block;
    margin: auto;
}

.nav-links ul li:hover::after{
    width: 100%;
    transition: 0.5s;
}

.nav-links ul li:nth-child(2):hover::after{
    background: none;
    width: 0;
}

nav .fa{
    display: none;
}

nav .fa-chevron-down{
    display: inline;
    margin-right: 6px;
}

.sub-menu-1{
    display: none;
}

.nav-links ul li:hover .sub-menu-1{
    display: block;
    position: absolute;
    background-color: #ff5733;
    margin-top: 15px;
    margin-left: -15PX;
}

.nav-links ul li:hover .sub-menu-1 ul{
    display: block;
    margin: 10px;
}

.nav-links ul li:hover .sub-menu-1 ul li{
    width: 150px;
    padding: 10px;
    border-bottom: 1px dotted #fff;
    background: transparent;
    border-radius: 0;
    text-align: left;
    text-transform: uppercase;
    font-weight: 500;
}

.nav-links ul li:hover .sub-menu-1 ul li:last-child{
    border-bottom: none;
}

.nav-links ul li:hover .sub-menu-1 ul li a:hover{
    color: bisque;
}

I added these two rules and it seemed to behave better.

This sets the defaults for everything (not required), so that we know what we are changing from

.nav-links ul, .nav-links ul li{
  position:relative;
  z-index:0;
}

This sets things to be on top when you hover them. I like to adjust z-index by at least 10 at a time, because it gives you room to insert between them at a later date if needed, without having to adjust everything else.

.nav-links ul li:hover{
  z-index:10;
}
