This is What Causes Slider Arrows and Dots to Not Appear on Your WordPress Site (and How to Fix It)
As a web developer, one of the most common issues I encounter is the Slick.js slider not displaying its navigation arrows and pagination dots on WordPress sites. This can be incredibly frustrating, as the slider is a crucial element for many websites, providing an engaging way to showcase products, services, or content.
In this comprehensive guide, we'll explore the common reasons why your Slick.js slider might not be showing the expected navigation controls, and provide you with actionable steps to resolve the problem. Whether you're a seasoned developer or just starting out, this article will equip you with the knowledge to troubleshoot and fix this issue effectively.
Understanding Slick.js and its Functionality
Slick.js is a highly versatile and feature-rich JavaScript library for creating responsive, mobile-friendly carousels and sliders. It's a popular choice among web developers due to its ease of use, customization options, and extensive documentation.
One of the key features of Slick.js is the ability to display navigation controls, such as arrows and pagination dots, to enhance the user experience and make it easier for visitors to navigate through the slider content.
However, sometimes these essential elements may not appear as expected, and that's where the problem arises. Let's dive into the common reasons behind this issue and how to address them.
Reason 1: Incorrect jQuery or Slick.js Initialization
The most common reason for the Slick.js slider not displaying the arrows and dots is an issue with the initialization process. Ensure that you have properly included the required jQuery and Slick.js library files in your WordPress theme or plugin.
Here's an example of how the initialization should look in your WordPress theme's functions.php file or in a custom plugin:
function my_custom_scripts() {
wp_enqueue_script( 'jquery' );
wp_enqueue_script( 'slick-js', 'https://cdn.jsdelivr.net/npm/slick-carousel@1.8.1/slick/slick.min.js', array( 'jquery' ), '1.8.1', true );
wp_enqueue_style( 'slick-css', 'https://cdn.jsdelivr.net/npm/slick-carousel@1.8.1/slick/slick.css', array(), '1.8.1', 'all' );
wp_enqueue_style( 'slick-theme-css', 'https://cdn.jsdelivr.net/npm/slick-carousel@1.8.1/slick/slick-theme.css', array(), '1.8.1', 'all' );
}
add_action( 'wp_enqueue_scripts', 'my_custom_scripts' );
function my_custom_slider() {
?>
<div class="my-slider">
<div><h3>Slide 1</h3></div>
<div><h3>Slide 2</h3></div>
<div><h3>Slide 3</h3></div>
</div>
<script>
jQuery(document).ready(function($) {
$('.my-slider').slick({
arrows: true,
dots: true,
// Add any other Slick.js options here
});
});
</script>
<?php
}
add_shortcode( 'my-custom-slider', 'my_custom_slider' );
In this example, we're properly including the jQuery library, the Slick.js JavaScript file, and the necessary CSS files. We then initialize the Slick.js slider on the .my-slider
element, ensuring that the arrows
and dots
options are set to true
.
If you're still experiencing issues, double-check that you've correctly included the required files and that the initialization is happening after the DOM has fully loaded.
Reason 2: Conflicting CSS Styles
Another common reason for the Slick.js slider not displaying the arrows and dots is conflicting CSS styles. Your WordPress theme or other plugins might be overriding the default Slick.js styles, causing the navigation controls to disappear.
To identify and resolve this issue, follow these steps:
-
Inspect the Element: Use your browser's developer tools to inspect the Slick.js slider element and its child elements, such as the arrows and dots. Check if there are any CSS rules that are hiding or overriding the desired styles.
-
Increase Specificity: If you find conflicting CSS rules, try increasing the specificity of your Slick.js styles to ensure they take precedence. You can do this by adding more specific selectors or using the !important
declaration.
Example:
.my-slider .slick-arrow {
/* Your Slick.js arrow styles go here */
}
.my-slider .slick-dots {
/* Your Slick.js dot styles go here */
}
-
Load Styles in Correct Order: Make sure that the Slick.js CSS files are being loaded before any other CSS files that might be interfering with the styles. You can achieve this by adjusting the order of your wp_enqueue_style()
calls in the WordPress functions.php file.
-
Use the !important
Declaration: As a last resort, you can use the !important
declaration to override any conflicting styles. However, this should be used cautiously, as it can lead to specificity issues down the line.
Example:
.my-slider .slick-arrow {
/* Your Slick.js arrow styles go here */
display: block !important;
}
.my-slider .slick-dots {
/* Your Slick.js dot styles go here */
display: flex !important;
}
By following these steps, you should be able to identify and resolve any CSS-related issues that are causing the Slick.js slider navigation controls to not appear.
Reason 3: Incorrect HTML Structure or Markup
In some cases, the Slick.js slider might not be displaying the arrows and dots due to issues with the HTML structure or markup. Ensure that your slider markup is correct and follows the expected Slick.js conventions.
Here's an example of a properly structured Slick.js slider:
<div class="my-slider">
<div>
<h3>Slide 1</h3>
</div>
<div>
<h3>Slide 2</h3>
</div>
<div>
<h3>Slide 3</h3>
</div>
</div>
Make sure that the .slick-arrow
and .slick-dots
elements are properly generated and positioned within the slider container. If you're using a WordPress plugin or a page builder, double-check the generated HTML to ensure it matches the expected structure.
Additionally, ensure that the Slick.js initialization script is properly placed, typically within a <script>
tag at the end of the page or in the functions.php file, as shown in the previous example.
Reason 4: Disabled Slick.js Options
The Slick.js library provides a wide range of options to customize the slider's behavior, including the display of navigation controls. If you've explicitly disabled the arrows
or dots
options during the initialization process, the corresponding elements will not be rendered.
Review your Slick.js initialization script and ensure that the arrows
and dots
options are set to true
. If you've set them to false
or removed them entirely, the navigation controls will not be displayed.
Here's an example of how to enable the arrows and dots:
$('.my-slider').slick({
arrows: true,
dots: true,
// Add any other Slick.js options here
});
By setting arrows: true
and dots: true
, you're instructing Slick.js to render the navigation controls as expected.

Reason 5: Responsive Design Issues
In some cases, the Slick.js slider may be hiding the navigation controls due to responsive design considerations. Slick.js provides various options to control the behavior of the slider on different screen sizes, and these settings might be causing the arrows and dots to disappear.
Check your Slick.js initialization script and ensure that the responsive options are configured correctly. For example, you might need to adjust the slidesToShow
, slidesToScroll
, or responsive
options to ensure the navigation controls are visible on all device sizes.
Here's an example of a Slick.js initialization with responsive settings:
$('.my-slider').slick({
arrows: true,
dots: true,
slidesToShow: 3,
slidesToScroll: 1,
responsive: [
{
breakpoint: 1024,
settings: {
slidesToShow: 2,
slidesToScroll: 1
}
},
{
breakpoint: 640,
settings: {
slidesToShow: 1,
slidesToScroll: 1
}
}
]
});
In this example, the slider will display three slides on larger screens, two slides on medium-sized screens, and one slide on smaller screens. Ensure that the navigation controls are properly configured for each of these breakpoints.
By addressing these common causes, you should be able to resolve the issue and get your Slick.js slider displaying the arrows and dots as expected on your WordPress site.
