I want to achieve a hover dropdown menu but I am kinda having a hard time to input it. I do have my code but base on my research I need to have a CSS which I don't have. Can someone help me?
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdownPortfolio" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" style="color:#fff;">
Project
</a>
<div class="dropdown-menu dropdown-menu-right" aria-labelledby="navbarDropdownPortfolio">
<a class="dropdown-item" href="portfolio-1-col.html">Ongoing</a>
<a class="dropdown-item" href="Completed 1stPage.html">Completed</a>
</div>
</li>
Is there anything that is lacking on my code?
