For my navigation bar, I want to create a feature where clicking on 'showreel' will cause the other two sections to appear. How can this be achieved using CSS?
Here is what my code looks like:
<li><a href="showreel.html">showreel</a>
<ul>
<li><a href="showreel.html">director</a></li>
<li><a href="showreel.html">cinematographer</a></li>
</ul>
