Mastering the slick.js Slider: How to Filter Slides Using Data Attributes

The slick.js slider is a powerful tool for creating responsive carousels on your website. However, developers often encounter challenges when trying to filter slides based on specific data attributes. If you’re trying to filter slides using data attributes but running into roadblocks, you're not alone! In this guide, we’ll walk you through a clear and effective solution to get your filtering feature up and running smoothly.

The Problem: Filtering with Data Attributes

Imagine you're building a slider that needs to display specific content dynamically. You decide to use data attributes to help filter which slides are shown based on user interaction or other criteria. However, you find that trying to filter the slides using something like the following jQuery code leads to unexpected results:

In this case, all slides disappear, despite the presence of multiple slides with data-test-id="1". Running the command to unfilter shows all slides again, indicating something is amiss with the filtering criteria.

The Solution: Adjusting Your Code

After some trial and error, a solution emerged that involves tweaking both your HTML structure and JavaScript filtering logic. Here’s how you can resolve the issue effectively.

Updated HTML Structure

Ensure Proper Class Usage: First, modify your HTML to ensure each slide has a consistent class that you can reference during filtering. Here’s an example of the adjusted HTML:

Updated JavaScript Logic

Refine Your JavaScript: Next, update your JavaScript logic to filter based on the data attribute using a function. Here’s how you can implement this:

By using a callback function, you can effectively check each slide’s data-test-id and filter accordingly. This approach allows for precise control over which slides remain visible.

Conclusion

In summary, if you're facing challenges filtering slides in the slick.js slider based on data attributes, make sure to follow these steps:

Ensure your HTML structure clearly defines each slide with appropriate classes and data attributes.

Use a filtering function in your JavaScript to dynamically evaluate which slides to show based on the data-test-id you’re interested in.

With these adjustments, your slider should work as intended, displaying only the selected slides while keeping the rest hidden. Don’t forget to test thoroughly to ensure everything performs as expected! Happy coding!
