Flickering on Submenu Click in WordPress Admin Menu (JavaScript/jQuery)

When customizing the WordPress admin menu to have a smooth, expandable/collapsible behavior on click, you may encounter an issue where the submenu flickers on click. This can be frustrating, especially when you're trying to create a seamless user experience. In this article, we'll explore the possible causes of this issue and provide a step-by-step guide on how to implement a click-to-toggle menu in WordPress using JavaScript and jQuery.

The flickering issue on submenu click in WordPress admin menu can be caused by several factors, including:

Inconsistent CSS styles: When you add custom CSS styles to the WordPress admin menu, it can sometimes conflict with the existing styles, leading to flickering.
JavaScript conflicts: If you're using multiple JavaScript libraries or plugins that interact with the WordPress admin menu, it can cause conflicts and lead to flickering.
Insufficient jQuery handling: jQuery is a powerful JavaScript library that's used extensively in WordPress. However, if you're not handling it correctly, it can lead to flickering issues.

To prevent flickering on submenu click, you need to ensure that your custom CSS and JavaScript code are properly integrated with the WordPress admin menu. Here are some steps you can follow:

Step 1: Add Custom CSS Styles

To add custom CSS styles to the WordPress admin menu, you can use the admin_menu action hook. This hook allows you to add custom CSS styles to the admin menu without modifying the existing styles.

function add_custom_css_styles() {
    ?>
    <style>
        /* Add your custom CSS styles here */
        .wp-menu-arrow {
            background-color: #333;
            color: #fff;
            padding: 5px 10px;
            border-radius: 5px;
            cursor: pointer;
        }
    </style>
    <?php
}
add_action('admin_menu', 'add_custom_css_styles');

Step 2: Add Custom JavaScript Code

To add custom JavaScript code to the WordPress admin menu, you can use the admin_menu action hook. This hook allows you to add custom JavaScript code to the admin menu without modifying the existing code.

function add_custom_javascript_code() {
    ?>
    <script>
        // Add your custom JavaScript code here
        jQuery(document).ready(function($) {
            $('.wp-menu-arrow').on('click', function() {
                $(this).toggleClass('active');
                $(this).next('.sub-menu').slideToggle();
            });
        });
    </script>
    <?php
}
add_action('admin_menu', 'add_custom_javascript_code');

Step 3: Handle jQuery Conflicts

To handle jQuery conflicts, you need to ensure that your custom JavaScript code is properly integrated with the existing jQuery code. You can do this by using the noConflict method.

function add_custom_javascript_code() {
    ?>
    <script>
        // Add your custom JavaScript code here
        jQuery(document).ready(function($) {
            $.noConflict();
            $('.wp-menu-arrow').on('click', function() {
                $(this).toggleClass('active');
                $(this).next('.sub-menu').slideToggle();
            });
        });
    </script>
    <?php
}
add_action('admin_menu', 'add_custom_javascript_code');

To implement a click-to-toggle menu in WordPress, you can use the following code:

function add_custom_javascript_code() {
    ?>
    <script>
        // Add your custom JavaScript code here
        jQuery(document).ready(function($) {
            $('.wp-menu-arrow').on('click', function() {
                $(this).toggleClass('active');
                $(this).next('.sub-menu').slideToggle();
            });
        });
    </script>
    <?php
}
add_action('admin_menu', 'add_custom_javascript_code');

This code adds a click-to-toggle behavior to the WordPress admin menu. When you click on the menu arrow, it toggles the active class and slides the submenu up or down.
