How Do I Add A Horizontal Submenu? Can't Figure It Out, Added Html And Css

Hey I would like to have a dropdown sub- menu in the same style, I know it's simple but I'm still new to making websites and I can't figure it out by myself. here's my HTML

Solution 1:

You closed the li that will hold the submenu ul too early.

Try working with this:

<nav>
        <ul>
            <li><a href="./index.html"><span class ="s2">Startpagina</span></a></li>
            <li><a href="./aanwinsten.html">Aanwinsten</a></li>
            <li><a href="./catalogus.html">Catalogus</a>
                <ul class="sub">
                    <li><a href="#">Pages</a></li>
                    <li><a href="#">Archives</a></li>
                    <li><a href="#">New Posts</a></li>
                </ul>
            </li> **<! - See the difference?-->**
            <li><a href="./uitlening.html">Uitlening</a></li>
            <li><a href="./reservatie.html">Reservatie</a></li>
            <li><a href="./suggestie.html">Suggestie</a></li>
            <li><a href="./contact.html">Contact</a></li>
        </ul>
    </nav>

Solution 2:

The problem lies here:

    <li><a href="./catalogus.html">Catalogus</a></li>
        <ul class="sub">
            <li><a href="#">Pages</a></li>
            <li><a href="#">Archives</a></li>
            <li><a href="#">New Posts</a></li>
        </ul>
    <li><a href="./uitlening.html">Uitlening</a></li>

You need to keep the <ul> inside the previous <li>. So make it this way:

    <li><a href="./catalogus.html">Catalogus</a>
        <ul class="sub">
            <li><a href="#">Pages</a></li>
            <li><a href="#">Archives</a></li>
            <li><a href="#">New Posts</a></li>
        </ul></li>
    <li><a href="./uitlening.html">Uitlening</a></li>

And now you can give the styling by positioning the <UL> tag in such a way that when you hover your mouse over the LI it shows up.

li.drop ul {display: none; position: absolute;}
li.drop {position: relative}
li.drop:hover ul {display: block; left: auto; top: auto;}
