How to Create a Collapsible Sidebar Menu in WordPress

WordPress is a great tool for creating a dynamic website, and one of its main draws is the flexibility it offers with customizable themes and menus. One of the more popular design trends in recent years is the collapsible sidebar menu, which can offer an elegant way to show a lot of content in a small amount of space. In this article, we’ll take a look at how to create a collapsible sidebar menu in WordPress.

Step 1: Set Up the Menu Structure

The first step to creating a collapsible sidebar menu in WordPress is to set up the menu structure. This is done by creating a custom menu in the WordPress admin panel under Appearance > Menus. You’ll need to create the main categories, sub categories and any other levels of hierarchy you wish to have in your menu. Do note that the WordPress menu system is limited in the number of levels that you can have – typically only two or three.

Step 2: Add the Collapsible Functionality

Once you have the menu structure set up, you can begin adding the collapsible functionality. This is done by adding special classes to the menu items. To make an item collapsible, the CSS class “expand” should be added. To make an item collapsible when a user clicks on it, the class “collapse” should be added. To make the menu items collapsible on hover, the class “hover” should be added. There are a few other classes as well, but these are the most commonly used.

Step 3: Add the Javascipt

The next step is to add the necessary Javascript code to the WordPress theme. This code will be responsible for adding the necessary functionality to make the menu items collapsible. This can be done by adding a “js” file to the theme containing the necessary code. The code should look something like this:

jQuery(document).ready(function() {
     jQuery('.expand').click(function() {

Step 4: Add CSS Styling

The last step is to add some CSS styling to make the menu look the way you want it to. This can be done by adding the necessary styles to the “style.css” file of your WordPress theme. Generally, a style for the “ul” and “li” elements should be added to make the menu look the way you want it to. In addition, some styling for the collapsed items is needed, as well as any special styling for active or hover items.


Creating a collapsible sidebar menu with WordPress is a relatively easy process, once you understand the steps involved. With just a few lines of code and some CSS styling, you can have a great looking, collapsible sidebar menu on your WordPress site.
