How to Change Sub-Menu Class Name in WordPress Navigation Menu? 🌐💻

If you're a WordPress user, you are probably familiar with the wp_nav_menu function, which allows you to easily create and display navigation menus on your website. But what if you want to change the class name of a sub-menu that is automatically generated by WordPress itself? 🤔

The Challenge 😓

By default, WordPress creates a <ul class="sub-menu"> for each child menu item in your navigation menu. However, there may be situations when you need to customize the class name to match your specific needs. Unfortunately, the solution is not as straightforward as changing the parent <ul> class name using the menu_class parameter. So, what's the solution? Let's find out! 🕵️‍♀️

Easy Solutions ✨

1. Use a Custom Walker Class 🚶‍♀️

One way to change the sub-menu class name is by using a custom walker class. A walker class is a way to customize the output of the wp_nav_menu function. Here's an example of how you can do it:

class Custom_Walker_Nav_Menu extends Walker_Nav_Menu {
    function start_lvl( &$output, $depth = 0, $args = array() ) {
        $indent = str_repeat( "\t", $depth );
        $output .= "\n$indent<ul class=\"your-custom-class\">\n";
    }
}

In the above code, we extend the Walker_Nav_Menu class and override the start_lvl method. We set the custom class name (your-custom-class) for the sub-menu <ul>. Note that you can replace your-custom-class with any class name of your choice.

To use this custom walker class, you need to pass it as the value for the walker parameter in your wp_nav_menu function. Here's an example:

wp_nav_menu( array(
    'theme_location' => 'primary',
    'walker' => new Custom_Walker_Nav_Menu(),
) );

By doing this, the sub-menu will now have the custom class name you specified.

2. Use JavaScript/jQuery 🌀

If you prefer a non-PHP solution, you can also use JavaScript or jQuery to change the sub-menu class name. Here's an example using jQuery:

$(document).ready(function() {
    $('.sub-menu').addClass('your-custom-class');
});

In this case, we use jQuery to select all elements with the class sub-menu and add our custom class name (your-custom-class) to them. Remember to include the jQuery library in your WordPress theme for this solution to work.
