I am experiencing an issue with this JS Fiddle https://jsfiddle.net/uvkt8z7j/16/ where the design gets distorted when I click on the dropdown menu while the screen is small. I want to maintain the same behavior as when the screen is large.
<body style="background-color: black;">
<div id='header'>
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<ul class='navbar-nav'>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<img src="https://png.icons8.com/ios/24/black/dining-room-filled.png">
</a>
<div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</li>
</ul>
<div class="collapse navbar-collapse" id="navbarNavDropdown">
<ul class="navbar-nav">
<li class="nav-item active">
<a class="nav-link menu-selection" href="#">STORE ORDER ONLINE <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link menu-selection" href="#">STORE INFO</a>
</li>
<li class="nav-item">
<a class="nav-link menu-selection" href="#">STORE LOCATORS</a>
</li>
</ul>
