I have a dropdown button in the center of my page, but when I click the dropdown, the actual dropdown part is still on the left side of the page. What's the issue?
HTML
<div class="row">
<div class="col-md-12 school-options-dropdown">
<div class="dropdown">
<button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">Choose a School
<span class="caret"></span></button>
<ul class="dropdown-menu">
<li><a href="#">Add your school</a></li>
<li><a href="#">Hello</a></li>
</ul>
</div>
</div>
</div>
CSS
div.school-options-dropdown {
text-align: center;
}
.dropdown {
text-align:center;
}
.dropdown-menu {
text-align: center;
}

You need to put the dropdown menu and the toggle button inside a .btn-group.
Also, Bootstrap provides the .text-center property to align the contents. This can be used on .school-options-dropdown, instead of manually adding CSS.
<script src=""></script>
<script src=""></script>
<link href="" rel="stylesheet" />
<div class="row">
<div class="col-md-12 school-options-dropdown text-center">
<div class="dropdown btn-group">
<button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">Choose a School
<span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Add your school</a></li>
<li><a href="#">Hello</a></li>
</ul>

.dropdown-menu-center {
right: auto;
left: 50%;
-webkit-transform: translate(-50%, 0);
-o-transform: translate(-50%, 0);
transform: translate(-50%, 0);}
If you don't want change your html code, this is css will solve your problem:
.dropdown {text-align:center;}
.button, .dropdown-menu {margin:10px auto}
.dropdown-menu {width:200px; left:50%; margin-left:-100px;}
If you are looking to center align the contents of the menu, then
ul.dropdown-menu>li {
text-align: center;
}
might do the trick.
Make sure you add the alignment in the entire div class defining it
With a Bootstrap 5 you can use JavaScript to override Popper.js after page loads like:
new bootstrap.Dropdown(document.getElementById('dropdown_button'), {
popperConfig: function () {
return {placement: 'bottom'}
}
});
Official documentation:
Here are placements you can override to:
