In jQuery, how to highlight a specific list item without also highlighting its children (another UL)?

I'm having trouble applying a hover effect to a UL without affecting the UL that is a child of one list item. I've tried various methods like using the > sign and the .not() selector, but so far nothing has worked.

Below is my simplified HTML structure:

<ul id="menu">
    <li class="menubox"><a href="#">Home</a></li>
    <li class="menubox"><a href="#">About Us</a></li>
    <li class="menubox"><a href="#" id="products">Products</a>
        <ul id="menu_products">
            <li><a href="#">1</a></li>
            <li><a href="#">2</a></li>
            <li><a href="#">3</a></li>
        </ul>
    </li>
    <li class="menubox"><a href="#">Forum</a></li>
</ul>

Here are some relevant CSS snippets:

#menu {
    position: relative;
    width: 250px;
}

ul#menu{
    list-style: none;
    margin-left: 0;
    padding-left: 0;
}

ul#menu li a{
    display: block;
    text-decoration: none;
    height: 40px;
}

#menu_products{
    list-style: none;
    display: none;
    margin-left: 0;
    padding-left: 0;
}

ul#menu_products li a{
    padding-left: 4em;
    height:30px;
}

And here's the jQuery code being used:

$("ul#menu > li").hover(
    function() {
        $(this).stop(true, true).animate({fontSize:"1.4em"}, 150);
    },
    function() {
        $(this).stop(true, true).animate({fontSize:"1.0em"}, 150);
    });

I also attempted using the selector ("ul#menu > li").not("#menu_products"), but it didn't work as expected. Any suggestions on how to achieve the desired result?

Answer №1

One potential solution is to solely expand the initial anchor.

Maintain your current HTML and CSS code, but modify the javascript to:

$("ul#menu li").hover(

function() {
    $(this).find('a').first().stop(true, true).animate({
        fontSize: "1.4em"
    }, 150);
}, function() {
    $(this).find('a').first().stop(true, true).animate({
        fontSize: "1.0em"
    }, 150);
});

Answer №2

To avoid any issues, consider making each submenu a fellow element of its parent in the HTML structure. This way, CSS inheritance will take care of styling the submenus without complications.

For example: http://jsfiddle.net/RCtFU/

<li class="menubox">
    <a href="#" id="varianten">Products</a>
</li>
<li class="menubox">  <!-- Consider changing the class for better clarity -->
    <ul id="menu_varianten">
        <li><a href="#">1</a></li>
        <li><a href="#">2</a></li>
        <li><a href="#">3</a></li>
    </ul>
</li>

Make sure to adjust classes and other attributes to clearly differentiate between main menus and their corresponding submenus.

Answer №3

If you're looking to enhance your web design skills, consider utilizing the power of the css3 :not() selector.

By incorporating this code snippet into your project:
$("ul#menu > li :not(ul)").hover(
function() {
    $(this).stop(true, true).animate({
        fontSize: "1.4em"
    }, 150);
}, function() {
    $(this).stop(true, true).animate({
        fontSize: "1.0em"
    }, 150);
});
