Folder-like menu css - css

Question

I'm working with a table-like menu but I can't do it. Here is my CSS.
I'm using bootstrap 5. I can't adjust the padding and also the color of the menu when it's active or not.
.top-nav{
margin-left:0px;
}
.top-bar a {
display: block;
text-align: center;
padding: 20px;
text-decoration: none;
}
.top-bar{
border-bottom: 100px solid white;
border-left: 0 solid transparent;
border-right: 80px solid transparent;
border-top: 80px;
height: 0;
width: 200px;
clip-path: inset(0% 0% 0% 0% round 15px 0px 0px 0px)
}
Here is my HTML
<div class="row top-nav">
<div class="col-md-3 top-bar">
<a class="fw-bold text-primary" href="#home">Users</a>
</div>
<div class="col-md-3 top-bar">
<a class="fw-bold text-primary" href="#home">Warehouse Admin</a>
</div>
<div class="col-md-3 top-bar">
<a class="fw-bold text-primary" href="#home">Sales Rep</a>
</div>
<div class="col-md-3 top-bar">
<a class="fw-bold text-primary" href="#home">Senior Sales Rep</a>
</div>
</div>
