  Hey CodedForFree!! actually you don't need all that Complexity for Menus like this , you can a lot with just css. and you don't have to duplicate menu.

  for example let's imagine that we have menu like so

  <nav role="navigation">
    <ul>
      <li><a href="#">Home</a></li>
       <li><a href="#">Features</a></li>
      <li><a href="#">About</a></li>
    </ul>
  </nav>
  
  

  Now, say we want a sub-menu dropdown on the second navigation item. and for interactivity reason, we need to change li to [button](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/button) element because is interactive by default which will make our life mush easy for implementing styling and accessibility , so we can include a list of links within that button:

  <button  type="button"><a href="#">Features</a>
        <ul class="dropdown">
          <li><a href="#">feature-1</a></li>
          <li><a href="#">feature-2</a></li>
          <li><a href="#">feature-3</a></li>
        </ul>
      </button>
  

  now when we have our button, In order to have the content hidden and displayed when we want it to be visible, we’ll need to apply some CSS. and we will take advantage of The :focus-within pseudo selector.

  button {
      position: relative;
      cursor: pointer;
  }
  
  
  button ul {
      display: flex;
      flex-direction: column;
      align-items: center;
      text-align: center;
      position: absolute;
      width: 9rem;
      left: 0;
     z-index: 3;
      list-style: none;
      padding: 1rem .25rem;
      margin-top: 1rem;
      border-radius: 0.5rem;
      visibility: hidden;
      opacity: 0;
      transition: all 200ms ease-in-out;
  }
  
  button:hover ul , button:focus-within ul {
      visibility: visible;
      opacity: 1;
  }
  
  /* Now, the submenu dropdown is hidden, but will be exposed and become visible when we hover over its */
  

  and for Mobile Navigation, you don't have to duplicate the navigation. My process on implement it like so ,

  I stared with nav like so.

  index.html

  <nav class="primary-nav">
            <button
              class="mobile-toggle"
              type="button"
              aria-expanded="false"
              aria-label="Menu"
            ></button>
  
            <ul class="nav-links" data-nav-toggled="false">
              <li><a class="nav-link" href="#">About</a></li>
              <li><a class="nav-link" href="#">Services</a></li>
              <li><a class="nav-link" href="#">Projects</a></li>
              <li><a class="nav-link" href="#">Contact</a></li>
            </ul>
          </nav>
  
  /* Notice That am using **data-attribute** to keep track of menu */ 
  

  style.css

  
  /* Base style FOR Navigation */
  
  .navigation {
    display: flex;
    align-items: center;
    justify-content: space-between;
    padding: 2rem;
  }
  
  .nav-links {
    list-style: none;
    display: flex;
    align-items: center;
    flex-direction: row;
    gap: 2rem;
  }
  .mobile-toggle {
    display: none;
  }
  
  
  /* Mobile Nav */
  
  
  @media (max-width:50rem) {
    .mobile-toggle {
      display: block;
      height: 1.75rem;
      width: 1.75rem;
      border: 0;
      outline: 0;
      background-color: transparent;
      background-image: url(/assets/images/icon-hamburger.svg);
      background-position: center;
      background-size: cover;
      cursor: pointer;
    }
    .mobile-toggle:focus {
      outline: auto;
      outline-offset: 3px;
    }
    
    .mobile-toggle[aria-expanded="true"] {
      opacity: 0.6;
  
    /* style the button when menu opened usually by changing background image to `close-btn`  icon*/  
    }
    
    .nav-links {
      flex-direction: column;
  /* Your styles for the mobile nav */
          position: fixed;
          z-index: 3;
       opacity: 0;
      visibility: hidden;
      transform: scale(0) rotateY(90deg);
      transition: all 400ms ease-in-out;
    }
      
  
    .nav-links[data-nav-toggled="true"] {
      opacity: 1;
      visibility: visible;
      transform: scale(1) rotateY(0deg);
  
  /* when menu opened */
    }
    
  }
  
  

  and that structure make our JavaScript simple like so .

  const mobileToggle = document.querySelector(".mobile-toggle")
  
  const navLinks = document.querySelector(".nav-links")
  
  
  mobileToggle.addEventListener("click", () => {
      const isToggled = navLinks.getAttribute("data-nav-toggled")
  
      if (isToggled === "false") {
          navLinks.setAttribute("data-nav-toggled", "true")
          mobileToggle.setAttribute("aria-expanded", "true")
      } else {
          navLinks.setAttribute("data-nav-toggled", "false")
          mobileToggle.setAttribute("aria-expanded", "false")
  
      }
  })
