I am having trouble positioning my dropdown in front of my sign up button and navbar. When I open the dropdown, it expands the navbar instead of overlapping it. It also offsets my sign up button. Below is the code for my navbar and a picture of what the issue looks like.

Basically, I want the dropdown to open without expanding the navigation bar.
<header>
<nav class="navbar navbar-dark bg-dark" aria-label="navbar">
<div class="container-fluid justify-content-between">
[Navbar Code Here]
</nav>
</header>
