How to Show/Hide Div in a WordPress Site Using jQuery
As a WordPress developer, you often need to add dynamic functionality to your website, such as the ability to show or hide content based on user interaction. This can be particularly useful for creating collapsible sections, accordion-style menus, or interactive elements that enhance the user experience.
In this blog post, we'll dive into the details of how to show and hide a div element on a WordPress site using jQuery. By the end, you'll have the knowledge and code samples to implement this feature on your own WordPress projects.
Understanding the Problem
Imagine you have a WordPress site with various sections or content blocks that you want to show or hide based on user interaction. This could be a sidebar widget, a section of the main content area, or even a modal or pop-up. Manually showing and hiding these elements can be time-consuming and can lead to a less-than-optimal user experience.
To address this, we can use jQuery, a popular JavaScript library, to add interactivity and dynamic behavior to our WordPress site. With jQuery, we can easily select elements on the page, listen for user events (such as clicks), and manipulate the visibility of those elements.
Step 1: Enqueue the jQuery Library in WordPress
Before we can use jQuery in our WordPress site, we need to make sure it's loaded and available. WordPress comes with jQuery built-in, so we can simply enqueue it in our theme's functions.php
file:
function my_theme_scripts() {
wp_enqueue_script( 'jquery' );
}
add_action( 'wp_enqueue_scripts', 'my_theme_scripts' );
This code ensures that the jQuery library is available for use in our WordPress site.
Step 2: Create the HTML Structure
Let's say we have a WordPress page with a button and a corresponding div that we want to show or hide. Here's an example of the HTML structure:
<div class="et_pb_column">
<button class="button closed">Toggle Content</button>
<div class="tab">
<p>This is the content that will be shown or hidden.</p>
</div>
</div>
In this example, we have a column (et_pb_column
) that contains a button and a div with the class tab
. The button has a class of button
and an initial class of closed
, which we'll use to track the state of the content.
Step 3: Add the jQuery Code
Now, let's write the jQuery code to handle the show/hide functionality. We'll use the code you provided in the introduction:
jQuery(document).ready(function( $ ){
// DOM selector for the column that wraps each .button and .tab
var col_sel = '.et_pb_column';
$( col_sel ).on("click", '.button', function(e){
var $btn = $( this ), // The current/clicked button.
tab = $btn.closest( col_sel ).find(".tab"), // The target tab.
aux, tmp;
e.preventDefault();
if (aux = $(".tab.visible", col_sel))
{ // Here we close the last/currently opened tab.
tmp = function() { alert( 'The last opened tab has been closed.' ); }; // Demo stuff. Remove this after done testing.
aux.removeClass("visible").slideToggle("slow", tmp); // I take it off and the hidden. Remove 'tmp' after done testing.
aux.closest( col_sel ).find('.button').toggleClass('opened closed');
}
if (aux[0] != tab[0])
{ // Here we open or close the target/current tab.
tmp = function() { var s = $( this ).is( ':visible' ) ? 'opened' : 'closed'; alert( 'The target tab has been ' + s + '.' ); }; // Demo stuff. Remove this after done testing.
tab.addClass("visible").slideToggle("slow", tmp); // I assign this class. Remove 'tmp' after done testing.
$btn.toggleClass('opened closed');
}
});
});
This code does the following:
- It selects the
.et_pb_column
elements, which are the containers for the button and the content div.
- It adds a click event listener to the
.button
elements within the .et_pb_column
containers.
- When a button is clicked, the code checks if there is a currently visible
.tab
element. If so, it slides it up and removes the visible
class.
- It then checks if the clicked button's corresponding
.tab
element is different from the last visible one. If so, it slides the .tab
element down and adds the visible
class.
- The code also toggles the
opened
and closed
classes on the buttons to reflect the state of the content div.
This functionality allows users to click on the buttons to show and hide the corresponding content divs within the .et_pb_column
containers.
Step 4: Style the Elements
To make the show/hide functionality visually appealing, you can add some CSS styles to the elements. For example:
.tab {
display: none;
}
.tab.visible {
display: block;
}
.button.opened::before {
content: "Hide ";
}
.button.closed::before {
content: "Show ";
}
This CSS code:
- Hides the
.tab
elements by default.
- Shows the
.tab
elements when they have the visible
class.
- Adds a "Hide " or "Show " prefix to the button text, depending on the button's state.

Real-World Example and Benefits
Imagine you have a WordPress site that displays a lot of product information. You could use the show/hide functionality to create collapsible product details sections, allowing users to expand and collapse the information as needed. This can improve the user experience by keeping the page clutter-free and making it easier for users to find the information they're looking for.
Another example could be a WordPress-powered website for a law firm. The firm could use the show/hide functionality to create an FAQ section, where users can click on question titles to reveal the corresponding answers. This can make the website more interactive and user-friendly, enhancing the overall experience for visitors.
By implementing the show/hide div functionality using jQuery, you can create more dynamic and engaging WordPress sites that cater to the needs of your users. This can lead to increased user engagement, improved accessibility, and potentially higher conversion rates.
