What is the best way to stop a UL element from inheriting the height properties of a drop down menu?

My sticky navigation bar is almost finished in terms of appearance and functionality. However, I encountered an issue when adding a drop-down menu within the links – it creates an invisible field that hides nearby text. Upon investigation, I found that the UL element adopts the full height properties of the drop-down, even when it's invisible. My aim is to make the drop-down menu its own separate entity to prevent this from happening. Ideally, the menu would have a higher z-index and only cover up content directly beneath it until the mouse moves away.

Additionally, I'm facing a problem where the drop-down menu appears while hovering over the space where elements should appear. This unintended effect seems to be the root cause of the issue.

Here is what happens with the drop-down menu present:

Here is what happens without it:

For reference, here is a JSFiddle. Please note that the logo display might vary, so visit the website for accurate representation. Also, the layout is not optimized for smaller screens yet, so expand the width until the navigation bar becomes horizontal.

Your .Dropdown element is hidden because it has the style of position: relative; and opacity: 0;, but it is still taking up space in the DOM.

To fix this issue with dropdown navigation menus, people typically use absolute positioning. When you position something absolutely, it no longer affects the layout of the DOM, but it needs to be anchored to a parent element with position: relative;. In this case, the parent element would be nav > ul > li.

To resolve this, update these styles:

nav  ul  li {
  position: relative;
  display: inline-block;
  margin: 15px;
  text-align: center;
}

.Dropdown {
    position: absolute;
    top: 100%;
    left: 0;
    opacity: 0;
    z-index: -1;
}

View this demo on JSFiddle for reference.

In your responsive styling in the fiddle, there was:

@media (max-width: 1200px) {
    nav ul li{
        display: inline;
   }
}

You should change that to:

@media (max-width: 1200px) {
    nav ul li{
        display: block;
   }
}

If you have not optimized for smaller screens yet, this style may just be for demonstration purposes.

By setting opacity: 0; or visibility: hidden;, the element is hidden but still reserves space on the page. Alternatively, if you add position: absolute; along with opacity: 0;, the space will not be reserved. Check out this link for more information:
