A common customization many WordPress users seek is to have the main menu bar appear at the top of their blog posts but disappear when scrolling. This feature, often seen on modern websites, enhances the user experience by offering easy navigation access while minimizing distractions during content consumption. If you’re facing an issue where the main menu bar won’t hide on scroll, this guide will help you implement a solution effectively.
WordPress themes come with various default settings and styles, and not all of them include advanced scrolling behaviors like a disappearing menu bar. Implementing this feature typically involves custom CSS and JavaScript, and sometimes theme modifications. Here's a step-by-step guide to achieve this functionality.

First, you need to ensure that your menu bar is styled correctly to support the hide-on-scroll functionality. This involves adding some CSS to your theme.
a. Go to Appearance > Customize in your WordPress dashboard.
b. Navigate to Additional CSS.
c. Add the following CSS code:
.navbar {
position: fixed;
width: 100%;
top: 0;
z-index: 1000;
transition: top 0.3s;
}This CSS sets the menu bar to be fixed at the top of the page with a smooth transition effect for hiding and showing.
Next, you'll need to add JavaScript to handle the hiding and showing of the menu bar based on scrolling.
a. Go to Appearance > Theme File Editor.
b. Select the header.php file (or footer.php, depending on your theme's structure).
c. Add the following JavaScript code before the closing </body> tag:
<script>
let lastScrollTop = 0;
const navbar = document.querySelector('.navbar');
window.addEventListener('scroll', function() {
let scrollTop = window.pageYOffset || document.documentElement.scrollTop;
if (scrollTop > lastScrollTop) {
// Downscroll
navbar.style.top = '-70px'; // Adjust based on your navbar height
} else {
// Upscroll
navbar.style.top = '0';
}
lastScrollTop = scrollTop;
});
</script>This script hides the menu bar when scrolling down and shows it when scrolling up. Adjust the -70px value to match your menu bar's height.
After adding the CSS and JavaScript, test your site to ensure the menu bar behaves as expected.
a. Visit a blog post and scroll down to see if the menu bar hides.
b. Scroll up to see if the menu bar reappears.
c. Adjust the CSS and JavaScript values if the menu bar is not behaving correctly (e.g., adjust the height in the JavaScript or the transition time in the CSS).

For more advanced control, you can use a plugin to add custom JavaScript or make use of additional libraries like jQuery if your theme supports it.
a. Install and activate a plugin like "Simple Custom CSS and JS".
b. Go to the plugin settings and add your custom JavaScript code in the plugin's JavaScript section.
If you prefer using jQuery, your JavaScript code would look like this:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
jQuery(document).ready(function($) {
var lastScrollTop = 0;
$(window).scroll(function() {
var scrollTop = $(this).scrollTop();
if (scrollTop > lastScrollTop) {
// Downscroll
$('.navbar').css('top', '-70px'); // Adjust based on your navbar height
} else {
// Upscroll
$('.navbar').css('top', '0');
}
lastScrollTop = scrollTop;
});
});
</script>Implementing a hide-on-scroll menu bar in WordPress involves adding custom CSS and JavaScript to your theme. By following these steps, you can achieve a seamless and professional look that enhances user experience on your blog posts. Always remember to backup your theme files before making changes and test thoroughly to ensure everything works as expected. If you encounter issues, consult your theme's documentation or seek help from the WordPress community for further assistance.
