How can I add Prev/Next buttons to articles in Webflow and link them to nearby articles/posts using a modified solution with additional variables?

To add Prev/Next buttons in Webflow that dynamically link to neighboring articles (e.g., blog posts), you'll need to enhance the default CMS functionality using custom JavaScript and Collection data.

1. Set Up Your Blog CMS Collection

• Make sure your Blog Posts Collection includes a Date (or custom Sort Order field) so entries can be ordered.
• This allows consistent logic when determining which post comes before or after.

2. Add Collection List for Indexing (Hidden)

• On the blog template page, add a Collection List that pulls in all blog posts, sorted by Date (or your preferred order).
• Limit items to, say, 100 (or your expected post limit), and set this list’s visibility to display: none so it stays hidden.
• Inside the list, give each item a unique attribute, such as:
• A wrapper div with attributes like data-slug, data-date, etc.
• Include a hidden field of the current post's slug, date, or other unique identifier.

3. Add Prev/Next Button Elements

• Add two button/link elements on the template page:
• Give one a class like .prev-button and the other .next-button.
• Set them initially to display: none, to be activated conditionally by JavaScript.
• Within each button, include a child element to dynamically insert the target post title (optional).

4. Use Custom JavaScript to Identify Nearby Posts

• Add JavaScript in the Page Settings or an Embed element in the page.
• On page load, your code will:
• Read all post data from the hidden Collection List.
• Match the current post (e.g., via window.location.pathname or post slug).
• Determine the position of the current post in the list.
• Set the Prev link to the post before it, and Next to the one after it.
• Update the link URLs and make the buttons visible.

Example logic flow (pseudocode-style, not full code):

• Get all elements with class .blog-index (from your hidden collection list).
• For each, store its slug, date, or custom order.
• Match the current post slug.
• Set prev = index - 1, next = index + 1.
• Use querySelector('.prev-button') and update href and text content accordingly.
• Set style.display = 'block'.

5. Optional: Add Custom Fields as Variables

• If you want to customize navigation logic (e.g., only within the same category or tag):
• Add Category, Tag, or other reference fields to your CMS.
• Include those fields as data-category, data-tag attributes inside the hidden list.
• In your JS, filter the array of posts to only include those matching the current post’s category or tag before calculating prev/next.

Summary

To create dynamic Prev/Next buttons in Webflow for CMS items, build a hidden Collection List on your CMS Template page to store post metadata, then use custom JavaScript to locate the current post and determine its neighbors. This allows full flexibility with navigation logic, enhanced further by using custom variables like category or tag matching.
