Currently facing a strange and frustrating challenge while working on transitioning code from Bootstrap 3 to Bootstrap 4. Specifically, I am dealing with a navbar that includes a button group on the right side (containing user name, login options, etc).
The issue arises when the button group is inserted into the navbar structure. If I place the button group outside of the navbar, it displays correctly with a vertical dropdown list. However, once I integrate the button group within the navbar, the dropdown list inexplicably turns horizontal.
It appears that certain parts of the code are interfering with each other, but I am unable to pinpoint the exact cause. After removing the PHP code and focusing solely on the HTML for Bootstrap 4, here is what I have:
<nav class="nav navbar-light bg-light navbar-right" style="margin-top: 3px !important;">
<div class="btn-group" role="group">
<button type="button" class="btn btn-default">hirsch</button>
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<span class="caret"></span>
</button>
<div class="dropdown-menu dropdown-menu-right" style="width: 200px;">
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href=""> <i class="fa fa-key" aria-hidden="true"></i> Change Password</a>
</li>
<li class="nav-item"><a class="nav-link" href=""> <i class="fa fa-user" aria-hidden="true"></i> Manage User ID</a>
</li>
<li class="nav-item"><a class="nav-link" href=""> <i class="fa fa-sign-out" aria-hidden="true"></i> Logout</a>
</li>
</ul>
</div>
</div>
</nav>
This piece of code functions as expected. However, inserting the following code snippet before or after the collapse section of the navbar causes the dropdown list to display horizontally, which is not the desired behavior:
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="">Home</a>
</li>
<li class="nav-item" >
<a class="nav-link" href="">Who's Who</a>
</li>
<li class="nav-item">
<a class="nav-link" href="">Disclaimer/Copyright</a>
</li>
<li class="nav-item">
<a class="nav-link" href="">Contact Us</a>
</li>
</ul>
<nav class="nav navbar-light bg-light navbar-right" style="margin-top: 3px !important;">
<div class="btn-group" role="group">
<button type="button" class="btn btn-default">UserName</button>
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<span class="caret"></span>
</button>
<div class="dropdown-menu dropdown-menu-right" style="width: 200px;">
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href=""> <i class="fa fa-key" aria-hidden="true"></i> Change Password</a>
</li>
<li class="nav-item"><a class="nav-link" href=""> <i class="fa fa-user" aria-hidden="true"></i> Manage User ID</a>
</li>
<li class="nav-item"><a class="nav-link" href=""> <i class="fa fa-sign-out" aria-hidden="true"></i> Logout</a>
</li>
</ul>
</div>
</div>
</nav>
</div>
</nav>
If you encounter the same issue, try copying and pasting these code snippets and observe the dropdown list behavior. The down-caret symbol in the button group should display vertically in the first example and horizontally in the second, despite being identical code. I'm struggling to identify the root of this problem even after spending considerable time analyzing it.
