How can I create a custom WordPress navigation menu with specific pages?

Creating a Custom WordPress Navigation Menu

Basic Approach

1. Register the menu location in your theme
2. Create the menu in WordPress admin
3. Add specific pages to the menu
4. Display the menu using wp_nav_menu()

Step-by-Step Solution

1. Register Menu Location

Add this code to your theme's functions.php:

function register_custom_menu() {
    register_nav_menu('custom-menu', __('Custom Menu Location', 'your-theme-textdomain'));
}
add_action('init', 'register_custom_menu');

2. Create and Display the Menu

Add this code where you want to display the menu (e.g., header.php):

<?php
if (has_nav_menu('custom-menu')) {
    wp_nav_menu(array(
        'theme_location' => 'custom-menu',
        'container'      => 'nav',
        'container_class'=> 'custom-menu-container',
        'menu_class'     => 'custom-menu',
        'depth'          => 2
    ));
}
?>

3. Add Custom CSS

Style your menu by adding this to your theme's stylesheet:

.custom-menu-container {
    margin: 20px 0;
}

.custom-menu {
    list-style: none;
    padding: 0;
}

.custom-menu li {
    display: inline-block;
    margin-right: 20px;
}

Best Practices

1. Always check if menu exists using has_nav_menu()
2. Use theme location instead of menu ID
3. Set appropriate depth for nested menus
4. Include fallback options for when menu doesn't exist
5. Make menus mobile-responsive

Security Considerations

1. Sanitize menu items using WordPress built-in functions
2. Use esc_html() for text output
3. Validate menu locations
4. Use proper capability checks for menu editing

Advanced Implementation

Here's a more feature-rich menu implementation:

function display_custom_menu() {
    $menu_args = array(
        'theme_location'  => 'custom-menu',
        'container'       => 'nav',
        'container_class' => 'custom-menu-container',
        'menu_class'      => 'custom-menu',
        'depth'           => 2,
        'fallback_cb'     => 'custom_menu_fallback',
        'walker'          => new Custom_Menu_Walker(),
        'items_wrap'      => '<ul id="%1$s" class="%2$s">%3$s</ul>'
    );
    
    wp_nav_menu($menu_args);
}

function custom_menu_fallback() {
    echo '<nav class="custom-menu-container"><ul class="custom-menu">';
    wp_list_pages(array('title_li' => ''));
    echo '</ul></nav>';
}

Common Pitfalls to Avoid

1. Not registering menu location
2. Using menu ID instead of theme location
3. Forgetting mobile responsiveness
4. Not providing fallback options
5. Incorrect depth settings for nested menus
