3 min read 23-11-2024

The Divi theme offers incredible flexibility, but sometimes you need that extra oomph to showcase your content. This article will guide you through creating a dynamic post slider in Divi that filters posts based on their tags. This powerful combination lets you create an engaging user experience, highlighting specific content categories with ease. We'll use Divi's built-in features and a little CSS magic to achieve this.

Planning Your Divi Tag-Filtered Post Slider

Before diving into the code, let's outline our strategy. We’ll leverage Divi's built-in post module and its filtering capabilities. We'll achieve the slider effect using a combination of Divi's modules and custom CSS.

Choosing Your Tags

Start by identifying the tags you want to use for filtering. Ensure your posts are correctly tagged within WordPress. Clear and descriptive tags make filtering much more user-friendly. Consider your content's organization and how users might navigate it.

Designing the Slider's Visuals

Think about the overall look and feel of your slider. Will it be a simple carousel or something more complex? Consider the following:

Color scheme: Match your slider's colors to your website's design.
Font styles: Choose fonts that are both visually appealing and easy to read.
Spacing and padding: Ensure there's enough white space between elements for a clean look.
Images: High-quality images are crucial for visual appeal. Optimize your images for web performance.

Building the Divi Tag-Filtered Post Slider

Now let's get our hands dirty! Here’s a step-by-step guide:

Step 1: Add a Divi Row and a Blank Module

Create a new row with your desired width and column structure (single column is recommended for this slider). Inside this row, add a blank module. This will serve as a container for our JavaScript and CSS.

Step 2: Add the Code to the Blank Module

Insert the following code into the blank Divi module's "Custom CSS" section. This code requires you to adjust the selectors to match your specific Divi page setup. Remember to replace your-tag-slug with the actual tag slug in your WordPress setup:

/* CSS for styling the slider */
.divi-tag-filter-slider {
  width: 100%;
  overflow: hidden;
}

.divi-tag-filter-slider .et_pb_post .et_pb_post_main_image {
  height: 300px; /* Adjust as needed */
  object-fit: cover;
}

/* JavaScript for filtering */
<script>
  jQuery(document).ready(function($) {
    $('.divi-tag-filter-slider .et_pb_button').click(function() {
      var tag = $(this).data('tag');
      $('.divi-tag-filter-slider .et_pb_post').hide();
      $('.divi-tag-filter-slider .et_pb_post[data-tag*="' + tag + '"]').show();
    });
  });
</script>

Step 3: Add the Post Module

Add a Divi post module below the blank module. Configure it to display posts. In the “Advanced” tab under “CSS ID & Class,” add the class divi-tag-filter-slider.

Step 4: Add Filter Buttons

Add another row below the post module, containing buttons for each of your tags. Use Divi’s button module, adding the following to the button code:

Data Tag Attribute: Add the data-tag="your-tag-slug" attribute to each button, replacing your-tag-slug with the correct WordPress tag slug.
Class: Add a class to each button to assist with styling.

For example: <button class="filter-button" data-tag="nature">Nature</button>

Step 5: Adjust Post Module Settings

In the post module settings, ensure you’ve selected your preferred post display settings. Importantly, check your “Number of posts to show”. This determines the posts that show in the slider initially. You may also need to check the “Show Images” option, and adjust image sizes.

Step 6: Add CSS for Responsiveness

Add further CSS to the blank module's custom CSS to handle responsiveness:

@media (max-width: 768px) {
  .divi-tag-filter-slider .et_pb_post .et_pb_post_main_image {
    height: 200px; /* Adjust as needed */
  }
}

Remember to adjust these media queries to suit your specific needs.

Troubleshooting and Further Customization

Tag Slugs: Double-check your tag slugs in WordPress. Incorrect slugs will prevent the filter from working correctly.
CSS Selectors: Ensure your CSS selectors accurately target the elements within your Divi structure. Use your browser's developer tools to inspect the elements and find the correct selectors.
JavaScript Conflicts: If you experience issues, check for JavaScript conflicts with other plugins.

This detailed guide empowers you to create a captivating post slider with tag-based filtering. Remember to experiment and adjust the CSS and JavaScript to match your specific design preferences and content. With a bit of patience and attention to detail, you'll have a stunning, interactive post slider enriching your Divi website.
