How to to display a list of categories with nested subcategories in WordPress

To display a list of categories with nested subcategories in WordPress, you can use the wp_list_categories() function. This function generates an unordered list (<ul>) with nested subcategories.

Here’s an example of how to use the function:

    'order' => 'ASC',
    'hide_empty' => true, // Set to false if you want to show empty categories
    'hierarchical' => true,
    'title_li' => '', // Set an empty title_li to remove the default 'Categories' title

echo '<ul>';
echo '</ul>';

Place this code snippet in the appropriate theme template file where you want to display the list of categories with nested subcategories, such as sidebar.php or index.php.

By default, the wp_list_categories() function generates a nested <ul> structure for subcategories, and WordPress will apply the appropriate CSS classes for styling.

Remember to always backup your files before making any changes, and test your changes on a staging site or local development environment before applying them to your live site.
